Answer:
So in order to increase the temperature of the material from 7° C to 19°C, heat required to the material is is 3 Q
Step-by-step explanation:
We know temperature is directly proportional to amount of heat applied to the substance.
Q = mcdT
Q = heat supplied
m=mass of the substance
c= specific heat capacity
dT= increase in temperature
Let let us consider two situations as dQ_1 and dQ_2
Therefore,




Q1=Q
then, Q2 = 3Q
So in order to increase the temperature of the material from 7° C to 19°C, heat required to the material is is 3 Q
