Question

If a 140g of copper wire gains 280J, with specific heat capacity of 4.184 J/gC, what is the change in temperature in the wire?

Answer 1

To find the change in temperature of the copper wire, you can use the formula for heat transfer:

Q = mcΔT

Where:

Q = heat energy transferred (in joules)

m = mass of the substance (in grams)

c = specific heat capacity (in J/g°C)

ΔT = change in temperature (in °C)

You're given:

Q = 280 J

m = 140 g

c = 4.184 J/g°C (specific heat capacity of copper)

Now, rearrange the formula to solve for ΔT:

ΔT = Q / (mc)

ΔT = 280 J / (140 g * 4.184 J/g°C)

ΔT ≈ 0.5°C

So, the change in temperature of the copper wire is approximately 0.5 degrees Celsius.
