The pressure rating of a car tire is typically given to be 210 kPa. This is based on an internal air temperature of 25\u00b0C.<\/p>\n

A driver decides to inflate the tires of his car to the rated pressure after driving at a high speed for some time, during which the internal air temperature has risen to 40\u00b0C.<\/p>\n

What will be the drop in pressure in each tire when the temperature has returned to 25\u00b0C?<\/p>\n

Answer B<\/strong><\/p>\n

Since V, n, R remains constant,<\/p>\n

P1\/ T_{1<\/sub>= p2<\/sub><\/em> \/ T2<\/sub><\/p>\n}

210 \/ (40 + 273) = p_{2<\/sub> \/ (25 + 273)<\/p>\n}

p_{2<\/sub> = 199.3 kPa<\/p>\n}

Drop in pressure = 210 –1<\/span>99.9 =10.1 kPa<\/p>\n
