Specific heat capacity

Question 1

What is Specific Heat Capacity?

Answer 1

The specific heat capacity (s.h.c) of a material is the amount of energy needed to raise the temperature of a substance by 1 degree

Question 2

What is the equation for energy supplied?

Answer 2

Energy supplied (J) = mass (kg) x s.h.c (J/kg°c) x temp. rise (°c)

Question 3

What is another equation for energy supplied?

Answer 3

Energy supplied = current x voltage x time

Question 4

What is the equation for Specific heat capacity (equation rearranged)?

Answer 4

Specific heat capacity = energy supplied/mass x change in temperature

Answer 8

4,200 J/kg°C

Question 9

If the shc of a material was 875J/kg°C what does this mean?

Answer 9

875 Joules of energy is required to raise a 1kg piece of this material by 1°C

Question 10

What is temperature?

Answer 10

Temperature is a measure of the average amount of kinetic energy in a molecule. (How hot something is)

Question 11
