Homework 3: Specific Heat Capacity Calculations
Calculating specific heat capacity
Here is the equation relating energy to specific heat capacity:
Independent
Learning: To extend
your revision for
Physics you should
complete a past
paper.
E=m×c×θ




E
E is the energy transferred in joules, J
m is the mass of the substances in kg
mm c θ
c is the specific heat capacity in J / kg °C
θθ
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?
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
Which substance requires the least amount of energy to raise its
temperature?
b
How much energy is needed to increase the temperature of 1kg of
water by 10C?
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?
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:
• Read a topic in the revision guide (e.g. about 3
Step 1 or 4 pages from the CGP revision guide).
• Make your own notes on this topic (mind maps/
Step 2 posters/spider diagrams/revision cards).
• Check your exercise book to see what you did
Step 3 on that topic and add to your notes.
• Cover up your notes and write out from
Step 4 memory. Repeat until you know it all!
• Complete practice exam questions on that topic
Step 5 from past papers or worksheets in your book.
• Tick off that topic on your checklist and move
Step 6 onto the next topic!

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.
Homework 5: Adaptations
Practice your exam technique using these questions.
FOUNDATION
HIGHER
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!
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 https://phet.colorado.edu/en/simulation/reactions-and-rates
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.
