Answer

Explanation:

Step1: Identify given values

Mass ( m = 500 , \text{g} ), specific heat ( c = 2.0 , \text{J/g}^\circ\text{C} ), temperature change ( \Delta T = -27 , ^\circ\text{C} )

Step2: Substitute into formula ( Q = mc\Delta T )

( Q = 500 \times 2.0 \times (-27) )

Step3: Calculate the product

First, ( 500 \times 2.0 = 1000 ), then ( 1000 \times (-27) = -27000 )

Answer:

-27,000 J
