What else can I help you with?
If a cold object is placed in a warm room what would happen?
A: Heat from the room will move to the cold object. B: Condensation will happen
What happens to hot and cold objects when they brought together?
If heat can flow between them, then heat flows from the hot one to the cold one. The temperature of the hot object falls, and the temperature of the cold object rises. What drives the transfer of heat is the difference in temperature, so as soon as both objects are at the same temperature, the process stops, and no more heat is transferred.
Heat will flow from a hot object to a cold object until the objects reach what?
In a closed system, yes. Both objects will be at the same thermal energy level, and neither will be able to release any to the other. In the real world, this is not the case, heat would continue to dissipate until the object reaches the same thermal energy level as the air around it, approximately.
Why is cold just the absence of heat?
"Cold" is a relative term, like "high" or "fast". It does exist as a qualitative term but only for comparison. It doesn't exist as a concrete object.
In which direction does heat transfer?
The direction that heat flows in is From a warmer object to a cooler object.
When you touch a cold object state whether heat energy flows from the object to your Hand or from your hand to the object?
Heat has the natural tendency to flow from a warmer to a colder object. If your hand is warmer than the "cold object", then heat will flow from your hand to that object.
Does heat travel from a hot object or cold object?
Heat always travels from a hot object to a cold object. This is based on the second law of thermodynamics, which states that heat naturally flows from regions of higher temperature to regions of lower temperature in an attempt to reach thermal equilibrium.
when a cold object is touched state whether the heat energy flows from the person's hand to the object or the object to the person's hand and why is it so?
When a cold object is touched, heat energy flows from the person's hand to the object. This is because heat always flows from the higher temperature (hand) to the lower temperature (object) in order to reach equilibrium. The sensation of coldness is due to the loss of heat energy from the hand to the colder object.
How heat is transferred between a hot and a cold object by conduction?
Heat is transferred between a hot and a cold object by conduction through direct contact. When the hot object touches the cold object, kinetic energy from the hot object's particles is transferred to the cold object's particles, causing them to vibrate and increase in temperature until thermal equilibrium is reached.
In order for heat to be transferred by conduction which of the following must occur A cold object must be heated with hot air. A hot object must be directly touching a cold object. The Sun must heat t?
A hot object must be directly touching a cold object for heat to be transferred by conduction. Conduction is the process of heat transfer through direct contact between particles of a substance. Heat flows from the hotter object to the colder object until thermal equilibrium is reached.
If a cold object is placed in a warm room what would happen?
A: Heat from the room will move to the cold object. B: Condensation will happen
What happens to hot and cold objects when they brought together?

What drives the transfer of heat is the difference in temperature, so as soon as both objects are at the same temperature, the process stops, and no more heat is transferred.
How does cold transform into heat?
When cold transforms into heat, it is due to the transfer of thermal energy. This process occurs when heat is added to a cold object, causing the molecules within the object to move faster and increase in temperature. This transformation is known as thermal energy transfer, where heat flows from a warmer object to a cooler object until they reach thermal equilibrium.
When does energy transfer from a cold object to a hot object?
Energy does not naturally transfer from a cold object to a hot object. Heat always flows from a hot object to a cold object in order to reach thermal equilibrium. This is described by the second law of thermodynamics.
How can heat be transferred between a hot and cold object by conduction?
Heat is transferred by conduction from a hot object to a cold object through direct contact. The molecules in the hotter object have more kinetic energy, causing them to vibrate and collide with the molecules in the colder object, transferring heat energy in the process.
What happens when a warm object touches a cold object?
When a warm object touches a cold object, heat energy is transferred from the warmer object to the cooler object. This transfer of heat causes the warmer object to cool down and the cooler object to warm up until they reach thermal equilibrium.
Does an object that feels cold to the touch contain thermal energy explain your answer?
Yes, an object that feels cold to the touch still contains thermal energy. The sensation of coldness is due to the object absorbing heat from your body, rather than the object lacking thermal energy.
