How would pressure change if area is doubled keeping the force constant?
Saharshakil
Since P = F/A, PA = F
So, if area is doubled, pressure is halved.

Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
What happens to the pressure of gas when the volume is doubled and no change in Kelvin temperature?
The pressure is decreased to 50 %.
How does the volume and pressure change in a tire after a long drive?
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.
Can the direction of velocity of an object change keeping the acceleration constant?
Yes. dv/dt = a=constant.
When the force applied on an object is doubled how does the pressure applied on an object change?
It will be double, if the area is unchanged. pressure=Force/area
What happens to volume when pressure is doubled?
The pressure of a gas would be reduced by half if the volume of the container doubled, provided that no other change occurred. Pressure and volume are inversely proportional. The relationship between the two is known as Boyle's law. In brief, the volume of a gas changes inversely with the pressure of the gas if the temperature and quantity of gas remain constant.
How is isothermal possible in a balloon?
Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.
When the double force applied on the object then how does the pressure exerted on the object change?
When the double force applied on the object then the pressure exerted on the object will also be doubled.
What special name is given to a heat change at constant pressure?
Enthalpy
