Question

You need to add ___ J of heat to raise the temperature of 100 grams water by 14 defrees celsius.

 

Answer 1

Change in Heat=Heat Capacity*mass of object*Change in Temperature.

 

For water=Heat Capacity per gram of Water is 4.184 J/g-C

 

for a temperature change of 14 degrees.

 

change in heat=(4.184 J/g-C)*(100 g)*(14 degrees C) or 5,857.6 J or 5.86 kJ
