the demensions of a classroom at 4.2 m * 3m* 2.5m assume the air in the adutiorium consists of a diatomic molecules with molar mass 28.9 g/mol

A) what are diatomic molecule?

B) find the number of molecules and the number of moles of the air in the room at atomsperic pressure and 20 degrees C.

C) find the average kinetic energy of the molecules

D) find the rms molecular speed

E) assumeing the room is airtight, how much energy must be transfered by hear to the gas to raise the temp by 5 degrees C.

F) how would your answer change from the previus problem for a monatomic gas?

A 1.00-L insulated bottle is full of tea at 91.0°C. You pour out a mug of tea and immediately screw the stopper back on the bottle. Find the change in temperature of the tea remaining in the bottle that results from the admission of air at room temperature. (Let the room temperature be 20.0°C and assume that you poured out 225 cm3 of tea. Take the molar mass of air as 28.9 g/mol and ρair = 1.20  10-3 g/cm3. Here we...

Consider a classroom filled with air. Let’s approximate air as an ideal gas of N2-molecules (nitrogen) at normal conditions (P = 1 Bar and T = 300 Kelvin). Suppose the room has dimensions of 10 m by 10 m by 10 m (a pretty large auditorium). Let us also assume that N2 molecule has 5 degrees of freedom (3 translational and 2 rotational). In this problem you will need to provide numeric answers up to the first significant digit. 2.1...

2 Equipartition The laws of statistical mechanics lead to a surprising, simple, and useful result — the Equipartition Theorem. In thermal equilibrium, the average energy of every degree of freedom is the same: hEi = 1 /2 kBT. A degree of freedom is a way in which the system can move or store energy. (In this expression and what follows, h· · ·i means the average of the quantity in brackets.) One consequence of this is the physicists’ form of...

Suppose that 4.8 moles of an ideal diatomic gas has a temperature of 1061 K, and that each molecule has a mass 2.32 × 10-26 kg and can move in three dimensions, rotate in two dimensions, and vibrate in one dimension as the bond between the atoms stretches and compresses. It may help you to recall that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas. a) How...

2. An aluminum scuba tank, which has an internal volume of 11.1 L, is filled with air to a pressure of 3000 psi when at room temperature (i.e. 20.0 OC). A diver takes the tank into seawater, where the water temperature is 46 degrees Fahrenheit (i.e. 8.00OC). To what pressure does the air in the tank drop? (The thermal coefficient of expansion for aluminum is 24.0x10-6 OC -1 .) Answer: 2880 psi Don't need #2, just #3 please. 3. For...

Neon gas (a monatomic gas) and hydrogen gas (a diatomic gas) are both held at constant volume in separate containers. Each container contains the same number of moles n of each gas. You find that it takes an input of 300 J of heat to increase the temperature of the hydrogen by 2.50°C. Part A How many modes does a single hydrogen gas molecule have? (Assume the vibrational modes are "frozen out"). 3, all rotational kinetic 6, 3 translational kinetic...
