on a cold wintry morning, the tires of a car appear flat. how has their volume changed overnight?

Answer 1

Molecules are slowed down when it is cold therefore they contract and therefore the tire looks low. When its heated back up it will return to prior state

Answer 2

There is a chemical law known as the "Ideal Gas Law" which relates pressure, volume and temperature. The equation is

PV = nRT

where,

P = Pressure
V = Volume
n = number of moles of gas
R = a constant
T = Temperature

Now, in this case, we are really looking at changes in these. Specifically, we are looking for the change in volume (tire appears flat) as the temperature changes (cold wintry morning). Thus, the equation can be written as:

P * (change in V) = n * R * (change in T)

Dividing both sides by P, we get the answer to the question above, specifically:

Change in V = (n * R * (change in T)) / P

Answer 3

whilst temperature decreases, the quantity will cut back because of the fact chillier air is extra dense and takes up much less area. which additionally potential the rigidity decreses too. additionally whilst temperature will develop, quantity will develop because of the fact warmer gases strengthen taking over extra desirable area and incresing the rigidity. thats why on warm days tires look over inflated.

Answer 4

Hi. Any gas will decrease in volume if it's temperature is decreased.

Answer 5

heat expands, so the tires shrink because of the cold.

Answer 6

v1/t1 = v2/t2
if t2 v2 = t2v1/t1

as t2 gets smaller, v2 gets smaller.
