specific heat capacity

Question 1

what is specific heat capacity?

Answer 1

the energy required to raise the temperature of 1kg of the substance by 1°C

Question 2

calculate the energy required to increase the temperature of 2 kg of water from 20°C to 100°C. The specific heat capacity of water is 4200J/KG°C

Answer 2

672000J
AE= m x c x A0
AE=2kg x 4200J/kg°C x 80°C
AE= 672000J

Question 3

what is the equation for specific heat capacity?

Answer 3

AE= m x c x A0
AE= change in thermal energy (J)
M= mass (kg)
C= specific heat capacity (J/kg°C)
A0= temperature change (°C)
