Follow the posted instructions - below.

Guide - How to Calculate Heat

Use the calculator on the formative and the guide (linked above) to help you calculate the heat for each question.

Follow the posted instructions - below.

Instructions:

The questions on the right will tell you the sample type and the initial/final temperatures. The other information - mass and specific heat - are found in the tables to the left.

  • Use the specific heat table for each substance and the mass of each sample in the two tables to the left to help you calculate the heat for each question to the right.

  • The question numbers in the second table (sample masses) align with the question numbers to the right (the actual questions).

Formula:

ΔT = Tf - Ti

Q = m x c x ΔT

m = mass

c = specific heat

ΔT = change of temperature

If you do not understand how to do the calculations use this guide.
