What amount of heat is released when the temperature of 450.0 g of a
Molodets [167]

Answer:

\boxed {\boxed {\sf 4038.48 \ Joules}}

Explanation:

Since we are given the mass, specific heat, and change in temperature, we should use this formula for heat:

q=mc\Delta T

The substance's mass is 450.0 grams, the specific heat is 1.264 J/g°C, and the  change in temperature is 7.1 °C.

m= 450.0 \ g \\c= 1.264 \ J/g \textdegree C\\\Delta T= 7.1 \ \textdegree C

Substitute the values into the formula.

q= (450.0 \ g)(1.264 \ J/g \textdegree C)(7.1 \ \textdegree C)

Multiply the first 2 values together. The grams will cancel out.

q= 568.8 \ J/ \textdegree C (7.1 \ \textdegree C)

Multiply again. This time, the degrees Celsius cancel out.

q= 4038.48 \ J

<u>4038.48 Joules</u> of heat energy are released.
