In the course of pumping up a bicycle tire, a liter of air at atmospheric pressure is compressed ISOTHERMALLY to a pressure of 7 atm. (Air is mostly diatomic and oxygen). (a) if the temperature is initially 300 K, what is the temperature after compression? (b) what is the final volume of this air after compression? (c) how much work is done in compressing the air?
An automobile tire is filled to a gauge pressure of 185 kPa when
its temperature is 20°C. (Gauge pressure is the difference between
the actual pressure and atmospheric pressure.) After the car has
been driven at high speeds, the tire temperature increases to
57°C.
Please help with both parts of this problem. Thanks!

A bicycle pump inflates a tire whose volume is 515 mL until its internal pressure is 6.30 bar at a temperature of 20.7 oC. a. How many moles of air does the tire contain? b.What volume of air (in L) at 1.01 bar and 20.7 oC did the pump transfer?
1) An automobile tire is filled to a gauge pressure of 196 kPa when its temperature is 20°C. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.) After the car has been driven at high speeds, the tire temperature increases to 51°C. (a) Assuming that the volume of the tire does not change, and that air behaves as an ideal gas, find the gauge pressure of the air in the tire. (b) Calculate the gauge pressure if...

Consider each of the following processes a. Does the temperature increase (+), decrease (-), or not change (0)? Are the work W and the heat Q positive (+), negative (-), or zero (0)? Does the thermal energy increase ) decrease (-), or not change (0)? Answer these questions by filling in the table. AT You drive a nail into a board with a hammer. You hold a nail over a Bunsen burner You compress the air in a bicycle pump...
A tank contains 500 kg of a liquid whose specufic gravity is
2. Determine the volume of the liquid in the tank.
1.29 A tank contains 500 kg of a liquid whose specific gravity is 2. Determine the volume of the liquid in the tank. 130 Clouds can weigh thousands of pounds due to their liquid water content. Often this content is measured in grams per cubic meter g/m3.Assume that a cumulus cloud occupies a volume of one cubic kilometer,...
Air in a cylinder is compressed to one-tenth of its original volume without change in temperature. What happens to its pressure? Imagine now that a valve is opened in order to restore the initial pressure value. What percentage of the molecules have escaped? Consider a 40,000 km steel pipe in the shape of a ring that fits snuggly all around the circumference of the Earth. We are heating now the ring so its temperature increased by 1 degree C. Now,...

Mixing Gases Consider two containers, . Both have volume 0.1 m3, and pressure 106 pa One contains monatomic (3 degrees of freedom) He at T 128 K and One contains diatomic (5 degrees of freedom) N2 at T- 258 K. A valve is opened allowing these two gases to mix. They are kept thermally isolated from the outside You can treat them as i deal gases. 1) What is the change in internal energy under this process?...
