# Question #1423e

##### 2 Answers

Q=mc(T'-T)

where:

Q=energy/heat

m=mass of the body

T'=final temperature of the body

T=initial temperature of the body

2000=240x(c)x(26-2)

c=2000/(240)(24) =0.3 J/g

Specific heat capacity is the quantity of heat in Joules or calories required to raise the temperature of a substance by one degree Celsius. The equation for heat capacity is Q = (c)(m)(

Q = the heat energy

c = specific heat capacity

m = mass

**Given** :

Q = 2000J

m = 240 g

**Unknown** :

c

**Equation** :

Q = (c)(m)(

**Solution** :

Divide both sides of the equation by m and

(rounded to one significant figure because 2000 J has only one significant figure)
