What happens to liquid water when it is cooled below zero degrees hasheat moved in or out of the liquid?
When liquid water is cooled below zero degrees Celsius, it begins to freeze and transform into ice. During this process, heat is released to the surroundings, as the water molecules lose energy and transition from a liquid to a solid state. This release of heat is known as the latent heat of fusion. Thus, heat moves out of the liquid water as it freezes.
Why do you need the freezer turned on to make Ice?
Ice will only form from water once water is cooled to below 0 degrees Centigrade. A freezer requires energy (ie it needs to be turned on) in order to pump heat out of the freezing compartment to lower the temperature in this compartment to below 0 degrees Centigrade. If the freezer is not turned on the temperature in the freezing compartment will be that of the room in which the freezer is kept.
Can air be warmed or cooled by the surface below?
This is a very easy question to answer . Yes the air can be cooled or warmed by the surface below it because say if there was to be a earthquake right now in the ocean the heating of the surfaceunder the water would cause the water the make enormous wave and for te world to shake and depending on how hot the surface is heating.
What condensers have lower head pressure air cooled or water cooled?
Water-cooled condensers typically have lower head pressure compared to air-cooled condensers. Water-cooled systems are more efficient in transferring heat, resulting in lower operating pressures and temperatures. This can help in reducing energy consumption and improving overall system performance.
What is the air-cooled condenser?
An air-cooled condenser is a type of heat exchanger that dissipates heat from a refrigerant by transferring it to the ambient air. It typically consists of a series of coils and a fan that circulates air over the coils to enhance heat transfer. Commonly used in refrigeration and air conditioning systems, air-cooled condensers are favored for their simplicity and lower installation costs compared to water-cooled systems. They are particularly effective in locations where water is scarce or expensive.
Why is the water used in the experimental procedures for the heat capacity of metals initially cooled several degrees below room temperature?
Cooling the water below room temperature helps to establish a stable baseline for the experimental procedures. This ensures consistency and accuracy in the measurements of the heat capacity of metals by minimizing any potential fluctuations in temperature. Additionally, starting with cooler water allows for more controlled heating up of the water during the experiment.
What type of heat pump coils are used outdoors?
Air cooled, water cooled and ground cooled

Fifty grams of water cooled from 50 degrees to 10 degrees if the specific heat of wayer is 4.2 hoe much was released?
The amount of heat released can be calculated using the formula: Q = mcΔT, where Q is the heat released, m is the mass (50g), c is the specific heat (4.2 J/g°C for water), and ΔT is the change in temperature (50°C - 10°C). Substituting the values, we get Q = 50g * 4.2 J/g°C * (50°C - 10°C) = 8400 J (or 8.4 kJ) of heat released.
How many btu's of heat are removed per hour when the water at a flow rate of 10 pounds per minute is cooled 15 degrees Fahrenheit?
74,970
What two places heat can be deposited in in a water-cooled condenser?
what two places heat be deposited in a water cooled condenser
Why and how does the water inside the chilled water pipes got cooled?
The heat gets removed from the H2O
What happens to heat stored in water vapor when it is cooled to its dew point?
When water vapor is cooled to its dew point, the heat energy is released as latent heat, causing the water vapor to condense into liquid water. This latent heat is the energy required for the phase change from gas to liquid, and is released back into the surrounding environment during condensation.
Is the heat intensity of water at 100 degrees celsius the same as the heat intensity of water 212 degrees Fahrenheit?
100 degrees celsius are equal to 212 degrees fahrenheit.

When you heat water to 100 degrees Celsius it does what?
Water boils at 100C (or 212F) at sea level.
