No.
You must take into account the mass of the objects AND the specific heat of the objects.

A short circuits in any system are always accompanied by a sudded?
current decrease
Does every transfer decrease momentum?
No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.
Whenever energy is transformed there is always an increase in the what?
entropy of the universe
When is the Law of Conservation of Energy valid?
Basically, always. There is no known way to create energy where there was none before (or to increase or decrease the amount of energy).
What effect does an increase in temperature have on a gas's volume and pressure?
As indicated by the Ideal Gas Laws, increasing temperature will tend to increase both volume and pressure. Of course, volume can't always increase, that depends upon the flexibility or inflexibility of the container that the gas is in, and if the volume does increase that will counteract the increase in pressure that would otherwise have happened. Temperature, pressure, and volume are all interconnected in a gas.

No. You must take into account the mass of the objects AND the specific heat of the objects.
Does water always have the same energy?
No. The energy you might be referring to is kinetic energy which is the energy possessed by individual water molecules. An increase in kinetic energy will be percieved as and increase in temperature. Similarly a decrease in kinetic energy will be percieved as a decrease in temperature.
Can we say mass vary with temperature for exp the mass of solid increase or decrease when temperature increase?
Mass of any chemical, in Chemistry, is always constant, no matter how much you change the conditions.

current decrease
Under which conditions will the volume of a given sample of a gas always decrease?
The Ideal Gas Law states that PV=nRT, where P=pressure, V=volume, n=number of moles of gas, R=the relativity constant, and T=temp in Kelvin. According to this law, volume (V) varies as V=(nRT)/P. Using this, we can determine that the volume would normally increase with an increase in the number of moles and/or an increase in the temperature and/or a decrease in pressure. Therefore, we can logically determine that the volume of a gas would decrease in the instance of increasing temperature if either the number of moles of gas was decreased or the pressure was increased (to an extent where the level of volume increase by temperature change has been overcome.)
Does every transfer decrease momentum?
No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.
The addition of heat energy to a system always causes the temperature of that system to increase.?
Yes. Adding heat will increase temperature.
In a geometric sequence where r and gt 1 the terms always increase.?
No, they do not. If the first term is negative, they always decrease.
Whenever energy is transformed there is always an increase in the what?
entropy of the universe
Which semiconductor have positive temperature coefficient?
With the increase in temperature if the resistance increases or the current in the circuit decreases then it is said to be have positive temperature coefficient .But in semi-conductors with the increase in temperature the electrons present in the valance band are excited and they would enter the conduction band for conduction . As the no. of charge carriers always increase in a semi-conductor , implies that the current always increases with the increase in temperature so the semi-conductor can never have positive temperature coefficient
Does the temperature always decrease with altitude?
No. A 2nd story floor doesn't have to always be colder than the first. It might even be warmer because heat rises and would get trapped. But if you're talking very large distances and very large areas, then in general, yes temperature will generally increase as you descend from very high altitudes.
The relationship between two quantities that increase or decrease together is called?
direct variation or positive correlation.
