The temperature gained and lost by two objects equals each other?

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.

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.
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 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.
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?
"temperature"
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.
What happens when two objects 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 one object heats another does the temperature increase of on 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 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.
Why do some objects feel colder than other objects of the same temperature?
The ones that feel colder, have better heat conduction.
If two objects at different temperature are in contact with each other what happens to their temperatures?
the same
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.
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 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.
