Look at the image above: I’m supposed to use the formula

Delta t=

PLEASE SOMEONE HELP

Student correctly measures the ΔT.

Q = 113.52 J

Explanation:

Given data:

Mass of gold is = 10.0 g

Initial temperature = T1 = 135°C

Final temperature = T2 =  47°C

ΔT = 88°C

Does ΔT is correct = ?

Solution:

Student is calculating the amount of heat released by gold.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Specific heat capacity of gold is 0.129 J/g.°C

ΔT = T2 - T1

ΔT = 47°C - 135°C

ΔT = -88°C

Student correctly measures the ΔT.

We can calculate the heat released by gold.

Q = 10.0 g× 0.129J/g.°C ×88°C

Q = 113.52 J
