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 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?

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 10C?

c How much energy is needed to increase the temperature of 1kg of

copper by 10C?

d A 1 kg block of copper is put in 2 kg of water.

How much energy is needed to increase the temperature by 10C?

HARD: Here you need to rearrange the equation using the formula triangle.

a 10,000 J is added to 1kg of water. How much does the water temperature increase by?

b 10,000 J is added to 1kg of copper. How much does the water temperature increase by?

c 10,000 J is added to 1kg of glass. How much does the water temperature increase by?

d 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:

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!

Homework 4: Temperature and Rates of Reactions

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 (named whatever you like!) reacting

at a low temperature. Then explain how this reaction changes as the temperature is increased.

The Story of Temperature and Rate of Reaction

In the beginning, there was

just some particles...

… when suddenly the

temperature began to

increase!

Success Criteria Grade D: Written or drawn how the particles move at low and high temperatures. Grade C: Described what happens to the rate of reaction when temperature is increased. Grade B: Explained what happens to the rate of reaction when temperature is increased. Grade A: Used the words kinetic energy and activation energy in your text.

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 5: 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.
