Does a refrigerator change heat into cold remove thermal energy from inside the refrigerator or cause thermal energy to disappear?
Thermal energy never disappears, but it can be moved from one place to another, which is what a refrigerator does. If you examine your refrigerator you will be able to observe that there are heat exchange tubes (usually on the back) which get hot as they pump heat from the interior to the exterior of the refrigerator.
Can magnets be put on a stainless steel refrigerator?
Magnets could be put on a stainless steel refrigerator as even non-magnet items would be able to become attached, especially with the modernday invention of tape.
What are the disadvantages of shielding a thermometer?
Shielding a thermometer may have some disadvantages, including: Inaccurate readings: If the thermometer is shielded improperly, it may affect the temperature readings by blocking heat or cooling that should be reaching the thermometer. Slow response time: If the thermometer is shielded too much, it may not be able to respond to temperature changes quickly, which can lead to inaccurate readings or delayed readings. Uneven temperature distribution: If the thermometer is shielded, it may not be able to measure the temperature of the surrounding environment accurately, which can lead to uneven temperature distribution. Difficulty in calibration: Shielding the thermometer can make it difficult to calibrate and maintain, which can affect its accuracy over time. Increased cost: Adding a shield to a thermometer may increase the cost of the device and add complexity to its design, which can make it more expensive to produce and maintain. In summary, while shielding a thermometer may be useful in certain circumstances, it can also have some drawbacks that may affect the accuracy and reliability of temperature readings. It is important to consider the specific application and environment before deciding whether to shield a thermometer or not.
Is a radiation pyrometer able to measure the temperature of sun?
No. The temperature of the sun cannot be measured by pyrometer. It is measured by a special device called Bolometer.
What happens to the altitude and boiling point as the pressure is increased?
As altitude increases, pressure decreases, so boiling point decreases, so the liquid would boil at a lower temperature and would not be able to get as hot and remain a liquid. As pressure is increased, boiling point increases, meaning the liquid could get hotter than normal and remain a liquid.PV=nRT - pressure x volume = the number of moles x constant x temperature
Why does leaf litter habitat able to maintain a constant temperature?
Leaf litter is a natural mulch. Mulch insulates against temperature extremes.
What helps mammals that are endotherms?
All mammals are endotherms. They are able to regulate their body temperature and maintain homiostasis. Say the temperature drops to a chilling 30°F, their body will try to keep them warm by staying at a constant temperature.
What is homeostasis What?
Homeostasis is the maintenance of a constant internal environment in organisms even when there are external changes. For example, the body is able to maintain its same temperature of 98.6 even when it is really cold.
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
How cow maintain homeostasis?
They are warmblooded creatures, like all mammals are, and able to maintain their internal levels through the energy they get from eating every day. This energy is called "metabolizable energy" which means that a cow is able to generate (never create) energy to keep her internal system at a constant temperature and functionable. Osmosis and Homeostasis is also important to maintain internal liquid levels

What is the purpose of water bath in distillation?
to convert the gas form of a substance into a liquid. If the temperature and boiling points are kept constant, then the substance with the lower boiling point will be able to be evaporated and condensed, thus separated. The condenser ultimately just cools the gas form of the substance so it may return to the liquid state.
Are cows endothermic?
Yes. Elephants maintain a constant body temperature like other mammals. They generate heat from their food. Of course they also need to cool down sometimes as they live in such hot places. This is why they have big ears. Blood circulates through them so it can lose heat to the surroundings.
Which animals are able to maintain a certain body temperature over a wide range of temperature in the environment?
warm blooded animals- mammals and aves
How is an able to maintain a constant speed when friction acts upon it?
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
Is a Dingo cold blooded?
dingoes are endotherms (an animal that can maintain a constant body temperature, regardless of the external temperate) which mean they are warm blooded. They are able to keep their internal temperature relatively stable due to a process called homeostasis.
How long does food last without electricity?
Your electricity do not eat the food. It depends on how hungry you are.
