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:

To solve this we assume that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant volume and number of moles of the gas the ratio of T and P is equal to some constant. At another set of condition, the constant is still the same. Calculations are as follows:

T1/P1 = T2/P2

P2 = T2 x P1 / T1

P2 = (47+273.15) x 780 / (27+273.15)

P2 = 831.97 mmHg

830 mm Hg

Explanation:

Hello! The new pressure would be approximately 830 mm Hg. Because of the decimal amount, it would remain this number. Hope this helps!
