6 Homework 3: Specific Heat Capacity Calculations Calculating specific heat capacity Here is the equation relating energy to specific heat capacity: E = m c θ E is the energy transferred in joules, J m is the mass of the substances in kg m c is the specific heat capacity in J / kg C θ ( theta ) is the temperature change in degrees Celsius, C EASY: For this section, just use the formula as it is above. Compound A is an imaginary solid. It has a Specific Heat Capacity of 1000 J / kg C a A 1 kg block of Compound A is heated, increasing its temperature by 1 C. How much energy has been added to the block? E m c θ Independent Learning: To extend your revision for Physics you should complete a past paper. b A 1 kg block of Compound A is heated, increasing its temperature by 10 C. How much energy has been added to the block? c A 1 kg block of Compound A is heated, increasing its energy by 1000 Joules. How much warmer does it get? d A 1 kg block of Compound A is heated, increasing its energy by 3000 Joules. How much warmer does it get? MEDIUM: Analyse some data to help you with the question. Specific Heat Capacity values Water 4,180 J / kg C Copper 390 J / kg C Glass 840 J / kg C a b c Which substance requires the least amount of energy to raise its temperature? How much energy is needed to increase the temperature of 1kg of water by 10 C? How much energy is needed to increase the temperature of 1kg of copper by 10 C? d A 1 kg block of copper is put in 2 kg of water. How much energy is needed to increase the temperature by 10 C? HARD: Here you need to rearrange the equation using the formula triangle. a b c d 10,000 J is added to 1kg of water. How much does the water temperature increase by? 10,000 J is added to 1kg of copper. How much does the water temperature increase by? 10,000 J is added to 1kg of glass. How much does the water temperature increase by? 20,000 J is added to 4kg of copper. How much does the water temperature increase by?

7 Summer Exam Revision Help To revise for your summer exam, you should use your revision guide, your past homework booklets and your exercise book. You should use the checklist earlier in this booklet to make sure you revise everything. Completing practice exam papers will help too. How to revise for Science: Step 1 Read a topic in the revision guide (e.g. about 3 or 4 pages from the CGP revision guide). Step 2 Make your own notes on this topic (mind maps/ posters/spider diagrams/revision cards). Step 3 Check your exercise book to see what you did on that topic and add to your notes. Step 4 Cover up your notes and write out from memory. Repeat until you know it all! Step 5 Complete practice exam questions on that topic from past papers or worksheets in your book. Step 6 Tick off that topic on your checklist and move onto the next topic!

8 acids bases salts Homework 4: Word Equation Task acid + metal carbonate salt + water + carbon dioxide EASY: Name the type of salts that these acids make. 1. Hydrochloric acid makes... salts. 2. Nitric acid makes... salts. 3. Sulfuric acid makes... salts. What acids were these salts made from? 1. Copper sulfate? 2. Copper chloride? 3. Silver nitrate? 4. Iron sulfate? MEDIUM: Complete these word equations. 1. calcium carbonate + hydrochloric acid 2. potassium carbonate + sulfuric acid 3. magnesium carbonate + nitric acid 4. sodium carbonate + hydrochloric acid HARD: Use the data in the table to write balanced symbol equations for the word equations from the MEDIUM questions. compound formula sulfuric acid H 2 SO 4 hydrochloric HCl nitric HNO 3 sodium hydroxide potassium hydroxide NaOH KOH calcium hydroxide Ca(OH) 2 sodium chloride NaCl potassium sulfate K 2 SO 4 calcium sulfate CaSO 4 1. magnesium nitrate Mg(NO 3 ) Independent Learning: To extend your learning you should look up word equations for other acid reactions, like acid and metals or acids and metal oxides.

9 Homework 5: Adaptations Practice your exam technique using these questions. FOUNDATION HIGHER

10 Independent Learning: Research the adaptations of an unusual animal or plant in the library or on the internet. In the space below, draw the animal and plant and explain its adaptations. Ask your teacher if you can t think of one!

11 Homework 6: Rates of Reactions and Concentration Use the boxes below to make a story about a particle in a chemical reaction. You can make cartoon drawings, use rhymes or simply write a story. The first five boxes are to explain the particle reacting at a low concentration. Then explain how this reaction changes as the concentration is increased. Success Criteria Grade D: Written or drawn how the particles are different at high and low concentrations. Grade C: Described what happens to the rate of reaction when concentration is increased. Grade B: Explained why that happens to the rate of reaction when concentration is increased. Grade A: Used the words successful collisions and activation energy in your text. The Story of Concentration and Rate of Reaction In the beginning, there was just some particles... when suddenly the concentration began to increase! Independent Learning: Extend your learning looking at rates of reactions simulations and models. Check out

12 Homework 7: Forces and Momentum This lesson you completed an experiment about forces and momentum. Write up your experiment using these subheadings. Hypothesis Say what you wanted to find out. Variables Say your independent, dependent and control variables. Conclusion Explain what you found out. Evaluation Explain if your test was fair, repeatable and reproducible. HANDY HELP: SENTENCE STARTERS In our experiment we wanted to find out if... We changed..., we measured and we kept... and... the same. In conclusion, we found out that... I think my test was/wasn t fair because... My experiment was/wasn t reproducible because... Independent Learning: Extend your learning by finding out more about momentum and how to calculate it. Search online or look in a Science text book.
