1(xiii)
Specific heat capacity of a substance X is 1900 Jkg-1°C-1 means:
- (a)Substance X absorbs 1900 J for 1°C rise in temperature
- (b)1 kg of substance X absorbs 1900 J heat for 1°C rise in temperature
- (c)1 kg of substance X absorbs 1900 J heat to increase the temperature
- (d)1 kg of substance X absorbs 1900 J heat to cool down by 1°C
