Question

758 j of heat are added to 0.750 kg of copper. how much does its temperature change?(unit=degrees c) PLEASE HELPPPPPPP MEEEEEE

Answer 1

`2.6^(\circ)C`

Step-by-step explanation:

When a certain amount of heat energy is supplied to a substance, the temperature of the substance increases according to:

`Q=mC\Delta T`

where

Q is the amount of heat energy supplied

m is the mass of the substance

C is the specific heat capacity of the substance

`\Delta T` is the change in temperature

In this problem:

Q = 758 J is the heat supplied

m = 0.750 kg is the mass

`C=385kg/JC` is the specific heat of copper

Solving for
`\Delta T`, we find the increase in temperature:

`\Delta T=(Q)/(mC)=(758)/((0.750)(385))=2.6^(\circ)C`
