Question

How much heat is required to raise the temperature of 1,500 g of water from 25°C to 52°C? The specific heat of water is 4.184 J/g-oC.

Answer 1

• Mass=1500g=m
• ∆T=52-25=27°C
• Specific heat capacity=c=4.184J/g°C

Apply thermodynamics

$\\ \rm\rightarrowtail Q=mc\delta T$

• Q is heat

$\\ \rm\rightarrowtail Q=1500(4.184)(27)$

$\\ \rm\rightarrowtail Q=169452J$
