Atire has a pressure of 780 mmhg at 27°c. if the tire is heated to 47°c on hot pavement, the new pressure will be: 310 mmhg 280 mmhg 830 mmhg 590 mmhg none of these

The new pressure is 830 mmHg

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

The equation used to calculate new pressure is:

where,

are the initial pressure and temperature of the gas.

are the final pressure and temperature of the gas.

We are given:

Putting values in above equation, we get:

Hence, the new pressure is 830 mmHg

explanation:

0.07 g/cm³

1.37 g/cm³
