# How do you calculate the amount of heat needed to increase the temperature of 250g of water from 20 C to 56 C? #C_g = 4.8 J/(C-g)#

#### Explanation:

- Given the data, the formula to use is

#Q=mCpDeltaT#

where:

#m=250g#

#DeltaT=T_2-T_1=56-20=36^oC#

#Cp=(4.8J)/(g*C)# - This case, just plug in given data to find the heat needed to raise the temperature of the water as provided in the problem.

#Q=(250cancel(g))((4.8J)/cancel((g*C)))(36^cancel(oC))#

#Q=43200J#

#Q=43.2kJ#
