Amass of gas under constant pressure occupies a volume of 0.5 m3 at a temperature of 20ﾟc using the formula for cubic expansion what will be the volume at a temperature of 45ﾟc without a change in pressure

To answer this question, we must use the equation for the volumetric expansion of gases at constant pressure. This equation is given by:

We know:

is the initial volume

ΔT is the temperature change = 45 ° -20 ° = 25 °

is the coefficient of gas expansion and is equal to 1/273

Then the final volume of the gas is:

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
