As the water boils at a certain temperature, phase change happen without change in its temperature. The heat associated is called the latent heat of vaporization. We obtain the heat required by multiplying the mass of the water to the latent heat of vaporization.
Heat = 0.018 x <span>2.3 x 10000000 = 41400 J</span>
You mean like a box sitting on a table.
One force is the force of gravity, pulling downward on the box.
Now, you know that the forces acting on the box must be balanced, because
if they're not, then the box would be accelerating. But it's just sitting there, so
there must be some other force, just exactly the right strength and direction to
exactly cancel the force of gravity on the box, so that the net force on it is zero.
The other force is the force of the table pushing upward on the box. It's called
the "normal force".
Answer:
The molecules in the gas would be completely stationary
Explanation:
The temperature of a gas is proportional to the average kinetic energy of its molecules, according to the equation (valid for an ideal monoatomic gas):
where
is the average kinetic energy of the molecules
k is the Boltzmann constant
T is the absolute temperature of the gas
For a gas at 0 Kelvin, T = 0: this means that the average kinetic energy of the molecules is also zero. But this means that the motion of the molecules has completely stopped, so the molecules are completely still.
