Question

if 20 grams of water at 20 degree celsius is supplied 20 calories of heat energy than the temperature of water is​

Answer 1

Answer:

Q = m × Cp × Change in Temp

Q = heat supplied in calories = 60 cal (given)

m = mass of water in gram = 15 grams (given)

Cp = Specific heat capacity of water at constant pressure (cal/gK) = 1 cal/gK (known)

Thus

60 = 15 × 1 × Change in Temp

Thus Change in Temp = 60÷15

Change in Temp = 4 K
