When heat is transferred from object A to object B, the temperature of object A decreases because it is losing thermal energy to object B. Heat transfer occurs from the object with higher temperature to the object with lower temperature in an attempt to reach thermal equilibrium.
What else can I help you with?
If two objects A and B of different size are both at a temperature of 500 K and are connected by a rod as in the image below. What will be the nature of transmission of heat?
Heat will flow from the object at a higher temperature (500 K) to the object at a lower temperature along the rod until both objects reach thermal equilibrium. The rate at which heat is transferred will depend on the thermal conductivity and surface area of the rod connecting the two objects.
Objects A and B are brought close to each other. Object A will soon become positively charged. Identify the charge that must transfer for this situation to occur.?
Electrons must transfer from object A to object B for object A to become positively charged. When electrons are transferred from one object to another, the object losing electrons becomes positively charged, while the object gaining electrons becomes negatively charged.
What has rubbing done to the charges on the objects shown in diagrams A and B?
Rubbing has transferred some charge between the objects in diagrams A and B. In diagram A, the initially neutral object loses electrons, becoming positively charged, while in diagram B, the initially neutral object gains electrons, becoming negatively charged.
Object A strikes object B the momentum of object B increase what happens to the momentum of object A?
You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
What happens when the temperature of a substance decreases significantly A. Most substances will expand. B. Most substances will gain atoms. C. Most substances will contract. D. Most substances will d?
C. Most substances will contract. When the temperature of a substance decreases significantly, its particles lose kinetic energy, causing them to move closer together. This results in a decrease in volume, known as contraction.
If object A is placed on top of object B and is the same temperature as object B How will heat flow between object A and object B?
In this case, no heat will flow between the objects. At least, there will be no "net" heat flow. The objects are said to be in thermal equilibrium, so that any heat exchanged by their molecules is balanced and there is no net change in temperature.

What is the relationship between wavelengths and temperature?
There is a relationship between the temperature of an object and the wavelength at which the object produces the most light. When an object is hot, it emits more light at short wavelengths while an object emits more light at long wavelengths when it is cold. The amount of radiation emitted by an object at each wavelength depends on its temperature.

If object A is inscribed in object B then what can be said about each?
Object B must be circumscribed about object A.
If object A is circumscribed about object B then what can be said about each?
.Object B must be inscribed in object A.
What happens to the temperature and density from point b to point b to c?
As you move from point b to point c, the temperature typically decreases while the density increases. This is often observed in atmospheric or oceanic contexts, where cooler temperatures at higher altitudes or depths lead to denser air or water. Consequently, the change in temperature and density can influence various physical and chemical processes in that environment.

Why newtons third can be stated as all forces act in pairs.?
Because that's what it is all about. If object "A" pulls on object "B", then "B" will pull back on "A".Because that's what it is all about.
