What determines whether an object is a net absorber or a net emitter of radiant energy at a given time?
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.
Will heat move from the ground to the atmosphere by conduction if the air is warmer than the ground?
No, heat will not move from the ground to the atmosphere by conduction if the air is warmer than the ground. Conduction involves heat transfer from a warmer object to a cooler object, so in this case, heat will not flow from the ground to the already warmer air.
Is 69F warmer than 74F?
No. Higher number= higher temperature. No, 74f is warmer than 69f.
Which is warmer -7 degrees or - 12 degrees?
-7 is warmer than -12
Is -6 Celsius warmer or colder than -16 Celsius?
-6 Celsius is 10 degrees warmer than -16 Celsius.
What will an object that is warmer than it's surroundings do?
An object that is warmer than its surroundings will transfer heat energy to its surroundings through conduction, convection, and radiation. This process will continue until the object reaches thermal equilibrium with its surroundings.
What will an object that is warmer then its surroundings do?
In that case, heat energy will tend to flow from that object to its surroundings.
An object that is warmer than its surroundings will absorb heat?
An object that is warmer than its surroundings will actually transfer heat to its surroundings, not absorb it. Heat transfer occurs from regions of higher temperature to regions of lower temperature in an effort to achieve thermal equilibrium.
What happens when the temperature of an objects surroundings change?
When the temperature of an object's surroundings changes, it can cause the object's temperature to also change. If the surroundings get warmer, the object will absorb heat and its temperature will rise. Conversely, if the surroundings get colder, the object will lose heat and its temperature will drop.
What method of heat transfer does a thermal camera use to detect an object?
A thermal camera utilizes radiative heat transfer to detect an object that is warmer than its surroundings.
What is the process of heat loss vs heat gain?
Heat loss occurs when the internal temperature of an object or space is higher than its surroundings, causing heat to transfer from the warmer object to the cooler surroundings through mechanisms like conduction, convection, and radiation. On the other hand, heat gain happens when the internal temperature is lower than the surroundings, resulting in heat transferring from the warmer surroundings to the cooler object or space. Both heat loss and heat gain play crucial roles in maintaining thermal equilibrium in systems.
What determines whether an object is a net absorb or a net emitter of radiant energy at a given time?
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.
What is the different temperature between an object and its surroundings?
The temperature difference between an object and its surroundings determines the rate at which heat is transferred between them, following the second law of thermodynamics. If the object is hotter than its surroundings, heat will flow from the object to the surroundings until thermal equilibrium is reached. Conversely, if the object is colder than its surroundings, heat will flow from the surroundings to the object until equilibrium is established.
Will an object will be a net radiator of energy when its thermal energy is less than that of its surroundings?
No, an object will not be a net radiator of energy when its thermal energy is less than that of its surroundings. In this case, the object will instead absorb thermal energy from its surroundings in an attempt to reach thermal equilibrium.
How many degrees warmer is 133 Fahrenheit than -122 Fahrenheit?
[object Object]
Will an object because of its temperature emitting more radiation than it receives from its surroundings undergo radiational?
Yes, an object emitting more radiation than it receives from its surroundings will undergo radiational cooling, as it is losing more energy than it is gaining. This will cause the object's temperature to decrease until it reaches thermal equilibrium with its surroundings.
What determines whether an object is a net absorber or a net emitter of radiant energy at a given time?
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.
