# Charles' Law Worksheet 1 Answer Key: Everything You Need To Know

## What is Charles' Law?

Charles' Law is a gas law that relates the volume and temperature of a gas. It states that at a constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature. This law is named after the French physicist Jacques Charles, who first formulated it in 1787.

### What is a Worksheet 1 for Charles' Law?

A worksheet 1 for Charles' Law is a set of questions and problems related to this gas law. It is designed to help students understand and apply the concepts of Charles' Law, including the mathematical relationships between volume, temperature, and pressure. The worksheet usually includes multiple-choice questions, calculations, and graphs.

### What are the Key Concepts of Charles' Law Worksheet 1?

The key concepts of Charles' Law Worksheet 1 include: - The direct proportionality between the volume and temperature of a gas at a constant pressure - The use of the Kelvin temperature scale to calculate the absolute temperature of a gas - The application of the ideal gas law (PV = nRT) to solve problems involving Charles' Law - The interpretation of graphs showing the relationship between volume and temperature of a gas

### What are some Sample Questions and Answers for Charles' Law Worksheet 1?

Here are some sample questions and answers for Charles' Law Worksheet 1: 1. A sample of gas occupies 10.0 L at 300 K. What is the volume of the gas at 350 K, assuming constant pressure? Answer: Using Charles' Law, we can write: V1/T1 = V2/T2. Solving for V2, we get: V2 = (V1 x T2) / T1 = (10.0 L x 350 K) / 300 K = 11.7 L. 2. A balloon is filled with 2.0 L of gas at 25°C. What is the volume of the balloon at 0°C, assuming constant pressure? Answer: We need to convert the temperatures to Kelvin first. 25°C + 273.15 = 298.15 K and 0°C + 273.15 = 273.15 K. Using Charles' Law, we get: V2 = (V1 x T2) / T1 = (2.0 L x 273.15 K) / 298.15 K = 1.83 L. 3. A gas at 10.0 L and 25°C is heated to 50°C. What is the new volume of the gas, assuming constant pressure? Answer: Again, we need to convert the temperatures to Kelvin. 25°C + 273.15 = 298.15 K and 50°C + 273.15 = 323.15 K. Using Charles' Law, we get: V2 = (V1 x T2) / T1 = (10.0 L x 323.15 K) / 298.15 K = 10.8 L.

### How can Charles' Law Worksheet 1 Help with Learning?
