options: 1)2hp 2)4hp .3)8hp 4)16hp

plz give correct procedure ​

Answer 1

Answer:

Explanation:

If by supplying a heat of Q to a substance of mass m, its temperature increases by Δt, then

Q∝

mΔt

or

Q=

cmΔt

where c= constant of proportionality , called specific heat capacity of the body.

Now, if

m=

1,Δt=

1 o

,

then,

Q=

c

therefore, specific heat is the heat required to raise the temperature of unit mass of substance by one degree Celsius.
