Latent heat and phase change
A physical process in which a conversion among the basic states or phases of matter, i.e., solid, liquid, and gas takes place under the effect of a certain temperature and pressure is referred to as a phase change. Generally, the phase change of a substance occurs when heat transfer takes place between the substance and its surroundings. Based on the direction in which heat transfer takes place, different types of phase changes can occur.
Triple Point of Water
The branch of physics in which observer deals with temperature related properties is called thermodynamics.
Boiling Point of Water
Everyday examples of boiling is, boiling milk, heating water. One would have observed that when we heat water it goes through various stages and at one point bubbles show in water, and water keeps splashing with bubbles bursting, we in layman terms say that water is boiling.
Freezing Point of Water
In general, the freezing point of water is 0° Celsius, or 32° Fahrenheit. This is the temperature at which water will ordinarily change from its liquid state to its solid state (ice). However, there are certain conditions that can affect the freezing point of water. For example, a liquid may be supercooled or contain impurities so that it does not freeze at the ordinary freezing point.
![(Ignore the effects of friction
The ride will be able to go faster because even though it has the same amount of total energy,
less mass will result in higher speeds.
The ride will go slower because having less mass means that the ride will start with less
gravitational potential energy at the top of the first hill.
C. The ride will go at about the same speed because roller coasters are controlled by machines
that compensate for the different mass of the passengers.
d. The ride will go at about the same speed because it will start with less gravitational potential
energy but it will require less kinetic energy to travel at the same speeds as usual.
