In the lab, you have nails with mass Mn and temperature Tn. You submerge those nails in the water with mass Mw and temperature Tw. Specific heat capacities of nails Cn and water Cw are Cn = 0.12 cal/gC Cw = 1.00 cal/gC Presume no energy loss (all energy transfer is only between water and nails). Find the resulting temperature of nails in the water after temperature is equalized given the following values: Mn = 139 g Tn = 119 C Mw = 119 g Tw = 27 C Enter 2 digits after decimal point.
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.
In the lab, you have nails with mass Mn and temperature Tn.
You submerge those nails in the water with mass Mw and temperature Tw.
Specific heat capacities of nails Cn and water Cw are
Cn = 0.12 cal/gC
Cw = 1.00 cal/gC
Presume no energy loss (all energy transfer is only between water and nails).
Find the resulting temperature of nails in the water after temperature is equalized given the following values:
Mn = 139 g
Tn = 119 C
Mw = 119 g
Tw = 27 C
