The pressure of the tyre after the temperature change is 0.89atm. Details about pressure can be found below.
How to calculate pressure?
The pressure of the tyre can be calculated using the following equation:
P1/T1 = P2/T2
Where;
- P1 = initial pressure
- P2 = final pressure
- T1 = initial temperature
- T2 = final temperature
According to this question, a tyre at 21°C (294K) has a pressure of 0.82 atm. Its temperature decreases to –3.5°C (269.5K).
0.82 × 294 = P2 × 269.5
241.08 = 269.5P2
P2 = 241.08 ÷ 269.5
P2 = 0.895atm
Therefore, the pressure of the tyre after the temperature change is 0.89atm.
