800mm Hg
Pressure and Volume are inversely proportional...
thus is volume is halved (400ml -> 200ml)
then pressure would double (400 mmHg -> 800 mmHg)
200 kPa x 50 m3 = 400 kPa x v
v (volume) = (200 x 50) / 400 = 25m3

p1.V1 / T1 = constant = p2.V2 / T2 (the 'Boyle&Gay-Lussac' Law)250*15/100 = 500*30/ T2T2 = 400K
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
Decrease the pressure of the surrounding environment. Thus, the force acting on the balloon from the outside decreases, allowing the air pressure that creates a force inside the balloon to have less of a counteracting force.

As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
8. Two cubic meters of a gas at 30 degrees Celsius are heated at a constant pressure until the volume doubles. What is the final temperature of the gas? 60.
A Direct Acting (DA) pneumatic thermostat increases branch line pressure as temperature increases. A Reverse Acting (RA) pneumatic thermostat decreases branch line pressure as temperature increases.
Velocity (meaning both speed and direction) remains constant (even if it is zero)
It is the theoretical constant pressure acting on the piston during one power stroke.
Boiling point
when the contact area is doubled keeping the force constant on the boy, there will be less impact on the body .
You must either increase the temperature of the liquid or decrease the pressure acting on the liquid (i.e., decrease the air pressure).
The object experiences no acceleration. That is, neither its speed nor the direction of its motion changes. That is, its velocity remains constant.
Use the ideal gas equation to solve this. PV= nRT. You will have to convert your pressure to atmosphere to use the constant R = 0.0821 L*ATM/mol*K. You know your initial pressure, volume, and temperature. Moles can be neglected (n) because they will stay the same. You also know your final pressure and final volume, so you can solve for final temperature.
It is usually a measure of how much one variable changes relative to changes in other variable(s). The pressure of an ideal gas depends on its temperature and volume. There are rates of change for pressurerelative to the temperature (with volume held constant),relative to the volume (with temperature held constant), anda multivariate rate of change when both can vary.Next, the rate of change need not be constant. For a body in accelerated motion, the rate of change of location (its velocity) varies with the acceleration. And that, in turn could vary with the force acting on the body.
The object remains in constant, uniform motion. That means its speed and direction of motion don't change. Note that its speed may or may not be zero.
