Which Formula Should I Use to Calculate the Kinetic Energy of Gases?

AI Thread Summary
To calculate the kinetic energy of gases in three tanks at a constant temperature of 25 degrees Celsius, the formulas E=3/2RT and E=3/2kT are discussed. The first formula is typically used for the total kinetic energy of a gas, while the second is for average kinetic energy. The confusion arises from whether the question requires the average kinetic energy or the total kinetic energy for each gas. Clarification is sought on which formula is appropriate based on the problem statement provided. Ultimately, the distinction between total and average kinetic energy is crucial for selecting the correct formula.

in the picture you can see Three different tanks contain Three different gases.
the temperature are equal to 25 Degrees Celsius in all the Three tanks,
and it not changing.

i asked to calculate the kinetic energy of the Three different gases.
so i thought to use this formula:3/2*RT but i also can use this formula :E=3/2kT but this formula is for average kinetic energy of the Three different gases no?

I'm confused about what formula is correct to solve my question.
thanks.

I would assume the question is asking for the average kinetic energy of the gas. However, I can't say for sure without seeing the exact problem statement.
 
hi.

well i gave you the exact problem statement as i got it.

and is not says to find the average kinetic energy of the gas, only to find the kinetic energy of each gas that given.

tell me if i correct, this formula:E=3/2kT is for average kinetic energy?
and this formula E=3RT/2 is just for kinetic energy of gas?

if i not asked to find the average kinetic energy only the kinetic energy of each gas so i need to use E=3RT/2?

thank you.
 
well sorry is speak about the average kinetic energy of the gas
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
