Suppose your bicycle tire is fully inflated, with an absolute pressure of 7.00×105 pa at a temperature of 21 °c. what is the pressure after its temperature has risen to 35.0ºc ? assume that there are no appreciable leaks or changes in volume. hint: at first, it may seem that not enough information is given, because the volume v and number of moles n are not specified. what we can do is use the equation twice: p0 v0 = nrt0 pf vf = nrtf . if we divide pf vf by p0 v0 we can come up with an equation that allows us to solve for pf . report the pressure in 105 pa. for example, if the pressure is 7.36*105 pa, just enter 7.36.
