# Chill Out: How Hot Objects Cool

Recommended for High School.

## Introduction

When you have a hot drink, you know that it gradually cools off. Newtonâ€™s law of cooling provides us with a model for cooling. It states that the temperature difference *T*_{diff} between a hot object and its surroundings decreases exponentially with time.

In the model *T*_{0} is the initial temperature difference, and *k* is a positive constant.

In this activity you will use a Temperature Probe to collect data as the warmed probe cools. You can then fit several mathematical models to the data.

## Objectives

- Record temperature versus time cooling data.
- Model cooling data with an exponential function.

## Sensors and Equipment

This activity features the following Vernier sensors and equipment.

### Option 1

### Option 2

### Additional Requirements

You may also need an interface and software for data collection. What do I need for data collection?
