If x calories of heat are supplied to 15 g of water, its temperature rises from 20°C to 24°C. If specific heat for water is 1 cal g⁻¹ °C⁻¹, then the value of x is...

Answer 1

Answer:

heat=mass×sp.heat×change in temp

x=15×1×(24-20)

x=15×4=60.

Answer 2

Answer:

x=60

Explanation:

Heat supplied=mass×specific heat × temp. difference.

m=15g. Cs=1÷{g×C}. temp. difference=24-20=4..

So, x=15×1×4=60
