A perfectly insulated calorimeter has the following parts placed inside of it: 0.250 kg of water at an initial temperature of 20 degrees celsius, 0.400 kg of aluminum at 26 degrees celsius and 0.100 kg of copper at 100 degrees celsius. The lid is then closed on the calorimeter and everything inside reaches an equilibrium temperature after a few minutes. What is the final temperature inside the calorimeter? Note: specific heat values that you may find useful, water 4186 J/(kg*K), copper 387 J/(kg*K), aluminum 900 J/(kg*K). Between 27 and 28 degrees celsius Between 24 and 25 degrees celsius O Between 29 and 30 degrees celsius Between 25 and 26 degrees celsius Between 30 and 31 degrees celsius Above 31 degrees celsius O Below 24 degrees celsius Between 26 and 27 degrees celsius
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.
