[QUOTE="Richie Smash, post: 5999955, member: 637801"] [h2]Homework Statement [/h2] A car tyre has initial temperature 23°C and inital pressure 2*10[SUP]5[/SUP] Pa After heating in the sun, temperature is now 34°C and final pressure is 2.1*10[SUP]5[/SUP]Pa Question asks, Calculate the ratio of new volume to old volume (V[SUB]1[/SUB]/V[SUB]2[/SUB]) if the pressure is held constant during the temperature rise stated above. [h2]Homework Equations[/h2] General Gas Equation (P1V1)/T1= (P2V2)/T2 [h2]The Attempt at a Solution[/h2] Using the general gas Equation I worked out the final pressure of 2.1*10[SUP]5[/SUP]Pa which was not orignially given. Now for the ratio my idea is as follows If the pressure is held constant, then V1/T1= V2/T2 which is a statement of charles Law. I'm not sure how to find the ratio but perhaps if the ratio of new to old volume would be the same as the ratio between new and old temperature? SO I would convert the celciusto kelvin by adding 273 and obtain 296 Kelvin initial temperature, and 307 K final temperature Then I would do this 307/296 and that would give me 1.04 to two significant figures as the ratio. Is this correct? I would like some assistance. [/QUOTE]
