Answer: Option C
Condensation
is a cooling process.
What is a cooling process?
[′kül·iŋ ‚präs·əs] (engineering)
Physical operation in which heat is removed from process fluids or solids
; may be by evaporation of liquids, expansion of gases, radiation or heat exchange to a cooler fluid stream, and so on.
Is a cooling process answer?
Evaporation
causes cooling is general process. the principle involved here is the matter must either gain or lose energy to change its state. Here molecules move from liquid to gaseous state and so it needs potential energy and kinetic energy. … Hence evaporation causes cooling effect.
Is boiling a cooling process?
As a liquid reaches its critical temperature, heat escapes through
rapid evaporation
, which can be considered a cooling process. When liquids turn into gases, excess heat out of the liquid is forced into boiling.
What is the process of cooling food?
The FDA recommends that food be cooled
from 135°F to 41°F (57°C to 5°C) in six hours or less
. … Food workers have the rest of the six hours to take food through the remaining temperature danger zone, from 70°F down to 41°F (21°C to 5°C). This entire cooling process is often called the two-stage cooling process.
What is the first step in the cooling process?
The first step is
to reduce the temperature from 135°F to 70°F within two hours of preparation
; the second step is to reduce the temperature from 70°F to 41°F or colder within an additional four-hour period. Total cooling time should never exceed six hours.
Is expansion a cooling process?
The frequency of atomic collisions decrease as
air expands
, therefore the air gets cooler. Temperature is just the average heat of a substance. … As the energy needed to increase it's temperature must be supplied from somewhere, the gas takes the energy from the surrounding system giving the effect of cooling.
Why is it a cooling process?
TL;DR (Too Long; Didn't Read)
Evaporation causes cooling because the process requires heat energy
. The energy is taken away by the molecules when they convert from liquid into gas, and this causes cooling on the original surface.
What is called warming process?
Condensation
is the warming process. Heat energy is released by the gas when it condenses into a liquid.
Is evaporation is a cooling process?
Evaporation is a
cooling process
because when water evaporates it takes the heat stored inside the substance with it.
How do we know that boiling water must be a cooling process?
its a cooling process because
water has a high specific heat and it absorbs a lot of heat energy to get boiled
. so it takes in a lot of heat energy from its surrounds along with the heat t that is being supplied to it so there would b a decrease in the surrounding temp.
What type of process is boiling water heating or cooling?
Our experience makes it easy for us to realize that to boil water or any liquid and thereby convert into a gas, heat is required and the process is
endothermic
. It is less intuitive to grasp that when a gas condenses to a liquid, heat is given off and the process is exothermic.
What type of process is boiling water?
Evaporation
only happens on the surface while boiling happens throughout the liquid. When a liquid reaches its boiling point bubbles of gas form in it which rise into the surface and burst into the air. This process is called boiling.
What are the 3 methods for cooling food?
- Ice-water bath and frequently stirring the food. …
- Ice paddles (plastic container filled with water and frozen) used to stir food in an ice-water bath.
- Adding ice as an ingredient (if water is an ingredient).
- Blast or tumble chiller.
Which foods increase body heat?
- Thermogenesis and Body Heat. In general, foods that take longer to digest can help raise your body temperature and make you feel warmer. …
- Eat Bananas. …
- Drink Ginger Tea. …
- Eat Oats. …
- Drink Coffee. …
- Eat Red Meat. …
- Eat Sweet Potatoes. …
- Eat Butternut Squash.
What is the 2 stage cooling process?
The two-stage cooling method is a Food and Drug Administration Food Code recommended procedure for cooling food in restaurants and foodservice establishments. In the two-stage cooling method,
food must be cooled from 140 °F to 70 °F within two hours and to 41 °F or lower within four hours
.
