The pressure of the tyre after the temperature change is 0.89atm. Details about pressure can be found below.
The pressure of the tyre can be calculated using the following equation:
P1/T1 = P2/T2
Where;
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.
