The specific heat capacity of liquid mercury is 0.14 J/gK.

How many joules of heat are needed to raise the temperature of 5.00 g of mercury from 15.0°C to 36.5°C?

There will be 15.05 Joules of heat released.

Explanation:

Step 1: Data given

Mass of mercury = 5.00 grams

The specific heat of mercury = 0.14 J/g*K = 0.14 J/g°C

Raise of temperature from 15.0°C to 36.5 °C

Step 2: Calculate heat released

q = m*c*ΔT

⇒ with q = The heat released in Joules

⇒ with m = the mass of mercury = 5.00 grams

⇒ with c = The specific heat of mercury = 0.14 J/g°C

⇒ with ΔT = The change of temperature = T2 - T1 = 36.5°C - 15.0°C = 21.5 °C

q = 5.00g * 0.14 J/g°C * 21.5 °C = 15.05 J

There will be 15.05 Joules of heat released.
