13 ! what is the effect of increasing the temperature by a factor of four on the velocity of a gas? the velocity of the gas will increase by a factor of 4. the velocity of the gas will decrease by a factor of 4. the velocity of the gas will increase by a factor of 2. the velocity of the gas will decrease by a factor of 2.

When gas law is combined with the formula for kinetic energy, we have
KE = ½mv² = (3/2)kT
We can rearrange the equation to calculate for the velocity of the gas molecules from the temperature of gas as 
v = (3RT/M)^(1/2)
We can see that the temperature is directly proportional to the velocity and that if the temperature is increased by a factor of four, the velocity of the gas will increase by a factor of 2.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
