Find the specific heat capacity of ice if 1.2 kg of ice absorbs 50.4 kJ of heat to raise its temperature from `-20^(@)C" to "0^(@)C`.

Text Solution

Verified by Experts

Here we use the relation,`Q=mxxsxxDelta theta`
Substituting Q = 50.4 kJ = 50400J
m=1.2kg
`Deltatheta=20^(@)C`
`Q=mxxsxxDeltatheta`
`s=(Q)/(mxxDeltatheta)=(50400)/(1.2xx20)=2100Jkg^(-1)K^(-1)`
