Air pressure at different room temperatures

AI Thread Summary
As room temperature increases, the air pressure in a sealed syringe also increases due to the direct relationship between temperature and pressure in a gas, as described by the ideal gas law (PV=k). The expansion of air at higher temperatures leads to a decrease in density, but this does not negate the increase in pressure. The value of the constant k remains the same, but the pressure will be higher at elevated temperatures for the same volume. Therefore, air pressure increases when room temperature rises. Understanding this relationship is essential for accurately interpreting the results of the physics practical.

Homework Statement


We did a physics practical in which a sealed syringe is compressed and pressure and volume of air inside is recorded. Given P=k/v, the gradient of the graph of P against 1/v is the constant,k. How would the value of k change if the same experiment is conducted at a higher room temperature?

Homework Statement


PV=k

The Attempt at a Solution


I know that in an enclosed space, air pressure increases as temperature increases. But does this also apply when talking about room temperature? Due to the expansion of the air, the density decreases right? So does room temperature increase or decrease? Any help is much appreciated.

Room temperature is a nice comfortable value for humans. Otherwise, there is nothing special.
 
Apologies, I wanted to ask if air pressure increase or decrease when room temperature increases?
 
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...
