Definition1/20
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .
however it obtained the unit of J/kg/k
The specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius.

'with two kittens' describe the cat. So, you should write 'is
sleeping'. But if you mean that all three of them are sleeping,
write 'A cat and his two kittens are sleeping'.
