Copper wires used to transport electrical current heat up because of the resistance in the wire. If a 14 g wire gains 52.7 J of heat, what is the temperature change of the wire in Celsius degree? Specific heat of Cu = 0.384 J/goC

the change in temperature is 9.8°C

Explanation:

mass of copper wire , m = 14g

specific heat of copper,c = 0.384J/g°C

Heat capacity q = 52.7J

Change in temperature =?

By substituting the above values in the expression below

the change in temperature will be calculate as,

q = mcΔT

Therefore,

ΔT = q / ( m × c)

Hence, the change in temperature is 9.8°C
