Question
The Ideal Gas Law states that Pressure = R x Density x Temperature:
P = x R x T
Using the Ideal Gas Law, explain why the can was crushed after it was heated under the blowtorch and then immediately placed in a bath of room-temperature water. Your explanation should include a discussion of how the temperature, density and pressure of the air inside the can changed before being heated, after being heated, and after being cooled.

Let Pi i Ti represent the pressure, density, and temperature of the air INSIDE the can.
Let Po o To represent the pressure, density, and temperature of the air OUTSIDE the can.
In the table below, indicate whether the pressure/density/temperature inside the can is >, =, or < the pressure/density temperature outside the can at each step (1-3) in the experiment (1 pt each). Include a separate written explanation of the reason for the conditions at each step (6 pts).
Write in the full expression: e.g., “Pi > Po“

1) Before being heated
2) After being heated
3) After being placed into water
Pressure

1) Before being heated
2) After being heated
3) After being placed into water
Explanation / Answer
Pi= Pressure Inside.
Po= Pressure Outside.
Di- Density Inside.
Do= Density Outside.
Ti =Temperature Inside.
To= Temperature Outside.
In this whole process their is an change in the Pressure where as Temperature and Density remains higher when the can is heated.
Pressure Density Temperature 1. Before being Heated. Pi = Po Di = Do Ti = To 2. After being Heated. Pi > Po Di < Do Ti > To 3. After being placed into water. Pi < Po Di < Do Ti > ToRelated Questions
