The heat energy absorbed by the colder object is roughly equal to the energy imparted by the warmer object (there is always loss), but the temperature change is based on the masses of the objects. If, for example, one gram of water at 60°C is mixed with one gram at 20°C, the mixture, ignoring losses, will be at 40°, there having been a heat energy transfer of 20 gram-calories. OTOH, if one gram of water at 60°C is mixed with one kilogram at 20°C, there will be a 40 gram-calorie transfer that will, again ignoring losses, result in the mixture being at about 20.04°C.
What else can I help you with?
Momentum of a system is conserved only when?
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
What is the property described by objects that are constantly moving around each other?
Objects that move around other objects in the universe are said to be orbiting it, or in orbit.
Why does CO2 make objects cold?
you mean the solid form of CO2?? Because heat is transferred to the dry ice from the other object, removing thermal energy and lowering its temperature.
What direction does thermal energy naturally flow?
Thermal energy flows from hotter objects to colder objects. This happens because on a microscopic scale, hot objects are the ones that move faster, and when a fast moving object collides with a slow moving object, kinetic energy is transferred from the faster object to the slower object. That takes us all the way back to the origin of physics, which is Isaac Newton's defintion: force equals mass times acceleration. So when you exert force on an object, it accelerates.
A box contains a collection of metal objects from a tomb How do you separate iron objects from metal objects?
You could use a magnet to separate a collection of metal objects from a tomb. Iron object and other ferrous metals will stick to the magnet while some other types of metals will not.
Heat flows from what temperature to what temperature?
High temperature always flows to low temperature, never the other way around.
What happens when two objects at different touch?
The object with the lower average temperature will take heat from the other object until both objects have the same temperature.
When two objects are touching each other and are at the same temperature there is no net change in either object's what?
When two objects at the same temperature are touching each other, there is no net change in either object's thermal energy. This means that there is no overall transfer of heat energy between the objects as they are in thermal equilibrium.
What happen when two objects at different temperatures touch?
The object with the lower average temperature will take heat from the other object until both objects have the same temperature.
When two objects are touching each other and are the same temperature there is no net change in either object what?
When two objects are touching each other and are the same temperature, heat energy will not flow from one object to the other. This is because there is no temperature difference to drive the transfer of heat. The objects will reach thermal equilibrium, where the average kinetic energy of their particles is the same.
Why should temperature be in kelvin in the equation pV equals nRT?
Most other temperature scales are not absolute - the lowest possible temperature is not zero.
What happens when there is a temperature difference between tow objects?
If they are in close contact, the hot object transfers heat to the cold object until both objects are equal in temperature. After which the temperature loss is reduced at the same rate until both objects have cooled to ambient temperature (the temperature of the surrounding air). If they are not in close contact, then most of the heat is dispersed into the air.
When one object heats another does the temperature increase of one object always equal the temperature decrease of the other object?
No. You must take into account the mass of the objects AND the specific heat of the objects.
What happens when there is temperature difference between two object?
If those two objects are in contact with each other, they will come to thermal equilibrium, at a temperature some place between the original temperature of the two objects. The actual final temperature will depend on the specific heat capacity of each object, the mass of each object and the temperature of each object.
When two objects are touching and transfer heat?
This is called conduction, where heat is transferred directly between the molecules of the objects in contact with each other. Heat flows from the object with higher temperature to the one with lower temperature until they reach thermal equilibrium. This process occurs until both objects have the same temperature.
What do thermometers measure other than air and water?
Thermometers can also measure body temperature, surface temperature of objects, and the temperature of gases and solids in various industrial processes.
In order for heat to be transferred between two objects by conduction?
the objects must be in physical contact with each other, and there must be a temperature difference between them. Heat will flow from the object with a higher temperature to the one with a lower temperature until thermal equilibrium is reached.
