Question

Write about specific heat​

Answer 1

ANSWER :

SPECIFIC HEAT :

The quantity of heat required to rise the temperature of 1 kg of substance through 1°c is called specific heat of that particular quantity or substance.

It is denoted by C or S

UNITS :

It's S.I unit is $\mathsf{J\: {kg}^{ - 1}}$

FACT :

Generally , quantity of heat absorbed by a body is proportional to rise in it's temperature i.e. if there is more mass then it takes more time to absorb heat than a colder one.

FORMULA :

Q=ms∆T

Where s is the specific heat of the body and q is the heat

Heat capacity = mass × specific heat capacity

Thermal capacity is the amount of heat required to rise the temperature of a body through 1°c . It's S.I unit is J/k

NOTE :

1 cal / g °c = 4.2 J / g °c

1 kcal / kg °c = 4200 J / kg °c
