Stefan-Boltzmann equation, power is proportional to T4, so if T is doubled power increases by a factor of 16.
2^4=16
No, the absolute pressure in a liquid of constant density would not double in this situation. This is because the atmospheric pressure is an independent variable, so it will keep the absolute pressure from doubling.
The gravitational force is doubled.
momentum is doubled, kinetic energy is quadrupled
When mass is doubled, gravitational attraction is doubled. There is a direct relationship.=========================Answer #2:Gravitational attraction always involves two objects, and the strength of thegravitational forces between them is proportional to the product of both masses.So . . .-- If one mass or the other is doubled, the forces are doubled.-- If both masses are doubled, the gravitational forces become 4 times as great.
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
if kelvin temp is halved, the volume is halved if pressure is constant.
No.
Charles' law states that the volume of a gas is directly proportional to its absolute temperature. So, when temperature is doubled, the volume of the gas is doubled. A gas burner increases the temperature of the air inside the balloon, which increases its volume, making it less dense the air around it, making it float.
Because kelvin temperature has a simple relationship with volume, according to Charles's' law if the kelvin temperature becomes doubled at constant pressure the volume of the gas also becomes doubled, this relation is not with Celsius or Fahrenheit temperature.
.. thenEITHER the pressure is halved for the same amount (moles) of gas,ORthe amount (moles) of gas is doubled at the same pressure,ORany valid combination of these possibillities.
The pressure is decreased to 50 %.

The volume is doubled.
For the pressure to remain the same, the temperature would double if the volume also doubled.
If the volume of a container of air is reduced by one half the partial pressure of the oxygen with in the container will be doubled. If the volume of a container of gas is reduced, the pressure inside the container will increase.
because the amount co2 is doubled every day and it makes a small hole in the ozone in the sky.
Assuming all other variables are kept the same, the volume would double.
