If we double the average kinetic energy of the gas atoms, what is the new temperature in ∘c?

-- Take the original temperature in °C .

-- Add 273.

-- Double the number you have now.

-- Subtract 273.  Now you have the new temp in  °C .

if kinetic energy is doubled than temperature of the gas must be double

Explanation:

As we know that average kinetic energy of the gas atom is known as

here we know that

f = degrees of freedom

R = ideal gas constant

T = temperature of the gas

now we know that average kinetic energy of the gas is double that of initial value

so from above formula we can say that kinetic energy is directly proportional to the temperature of the gas

so here if kinetic energy is doubled than temperature of the gas must be double

increases it

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
