Question

A balloon with a volume of 2.0 L at 25°C is placed in a hot room at 35°C. The pressure on the balloon is constant at 1.0 atm.1. How does the volume of the balloon change after moving it to the hot room?

Answer 1

The volume of the balloon will increase to 2.8 L after moving it to the hot room.

Step-by-step explanation:

According to Charles's Law, the volume of a gas is directly proportional to its temperature, assuming constant pressure. In this case, when the balloon is moved to the hot room, the temperature increases from 25°C to 35°C. Therefore, the volume of the balloon will increase as well.

Let's use the formula for Charles's Law: V1/T1 = V2/T2

Given: V1 = 2.0 L, T1 = 25°C, T2 = 35°C

Using the formula, we can find V2:

V2 = V1 * (T2/T1) = 2.0 L * (35°C/25°C) = 2.8 L

Therefore, the volume of the balloon will increase to 2.8 L after moving it to the hot room.
