Heat Capacity and Calorimetry

AP Chemistry· difficulty 3/5

A 1.00 g sample is combusted in a bomb calorimeter.

bomb C_cal = 8.50 kJ/°C; ΔT = +4.20°C

What is the heat released by the sample?

  • A

    +35.7 kJ (absorbed)

  • B

    2.02 kJ

  • C

    35.7 kJ

    check_circle
  • D

    8.50 kJ

Explanation

q_cal = C_cal·ΔT = (8.50)(4.20) = 35.7 kJ absorbed by calorimeter, so 35.7 kJ released by the sample.
