E-CodeCalorimetry: mixing and melting ice — a TI-84 Plus CE program
CALORIM is a TI-BASIC program for the TI-84 Plus CE. Mix two substances (mass, specific heat, temperature) to the final temperature and heat exchanged, or drop ice below 0 °C into warm water: the final temperature, or how much ice melts when it can't all melt.
What it asks for and what it shows
It asks for 6 values at its prompts, after you pick option 1 from its menu. In the example below it shows TF (C), Q1 (J), Q2 (J).
Example run
One of its oracle test cases: “hot water and aluminum”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Menu | option 1 |
| Input 1 | 200 |
| Input 2 | 4.184 |
| Input 3 | 80 |
| Input 4 | 150 |
| Input 5 | 0.897 |
| Input 6 | 20 |
| The screen shows | |
TF (C)= | 71.6888866 |
Q1 (J)= | -6954.739692 |
Q2 (J)= | 6954.739692 |
How it's checked
5 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 24 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “Calorimetry: mixing and melting ice” (CALORIM).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
