2.2 specific heat capacity

Question 1

What is the specific heat capacity of a substance?

Answer 1

The specific heat capacity of a substance is the amount of energy needed to change the temperature of 1 kg of the substance by 1°C

Question 2

How do you calculate the energy needed to change the temperature of mass by? A0

Answer 2

AE = m x c x A0

Question 3

How does the mass of an object affect the temperature increase when heated?

Answer 3

The greater the mass of an object the more slowly its temperature increases when it is heated

Question 4

How do you find the specific heat capacity ( C )of a substance?

Answer 4

Use a joulemeter and a thermometer to measure AE and A0 for a measured maths the use
c = AE / m A0

Question 5

What does AE stand for?

Answer 5

Energy transferred (joules, j )

Question 6

What does C stand for?

Answer 6

Specific heat capacity (joule per kilogram per degree Celsius, J/kg °C)

Question 7

What does A0 stand for?

Answer 7

Temperature change (degree Celsius, °C)
