- Show that by using expressions for vrms and pressure based on kinetic theory of gases you can derive the ideal gas law.A cup of hot coffee sits on your desk. Assume that the thermal energy in the coffee can be converted with an efficiency of 100%% to gravitational potential energy of the coffee-Earth system-enough so that the coffee rises up above the rim of the cup. Let the height of the coffee rise by 3.4 cm. Find the magnitude of the drop in temperature needed to accomplish this energy conversion. Use c = 4180 J/kg⋅C for coffee.Freeze drying is a process in which substances, such as foods, are dried by placing them in a vacuum chamber and lowering the atmospheric pressure around them. How does the lowered atmospheric pressure speed the drying process, and why does it cause the temperature of the food to drop?

(a) How much work (in J) do you do in one stroke if the average gauge pressure is 2.40 x 10° N/m (about 35 psi)? J (b) What average force (in N) do you exert on the piston, neglecting friction and gravity? N Additional Materials Reading ES Scanned with CamScanner Submit AnswerAssume that when in thermal equilibrium (i.e. the temperature is not changing) Mars absorbs all of the heat it receives from the Sun and then re-radiates it as black body radiation from all parts of its spherical surface. Assuming that Mars' temperature is uniform across all of its surface, calculate the temperature on Mars. The Stefan-Boltzmann constant σ=5.7×10−8 W m−2K−4.To answer this question you need to balance the total energy per second being absorbed by Mars with the total energy per second being radiated by Mars. Key: Flux of radiation from the Sun at Mars' orbital radius is 597 W m-2. The luminosity of the Sun Ls = 3.8×1026 W. Mars orbits at a distance of 2.25×1011 m (1.5 AU) from the Sun. Total amount of radiative energy per second is 2.2 x 1016 W.
- Mike is trying to determine the amount of work his experimental air compressor is doing. He finds that the amount of work done (W) depends on the rate of change in pressure created by the pump (dP/dt) with respect to time, the volume of air inside the pump (V) and the speed at which air moves out of the pump (v).Q24: Which of the following is a statement of the fist law of thermodipanis!O The disorder of the universe is constantO The universe is stableO Energy cannot be transferred or transformed.O Energy cannot be created or destroyed.Jason is investigating how energy from the Sun drives convection in the atmosphere. He wants to draw a diagram showing what happens to air when it is heated by the Sun during the process of convection. Which diagram should he draw? A He should draw a diagram that shows cool air in Earth's atmosphere rising. B He should draw a diagram that shows cool air near Earth's surface rising. C He should draw a diagram that shows warm air in Earth's atmosphere sinking. D He should draw a diagram that shows warm air near Earth's surface rising.
