Answer:
C. Equals the sum of all forms of energy contained within the system.
D. Equals the heat entering the system at constant volume.
E. Equals the heat entering the system plus the work done on the system
Explanation:
Internal energy is defined as the sum of internal kinetic energy and internal potential energy, that is, the energy contained within the system.
The first law of thermodynamics relates the change in the internal energy with the heat entering the system (Q) and work done on the system (W), with the following expression:
If the system is at constant volume the work done is zero. Therefore, the heat entering the system increases its internal energy:
Yes its a part of circular motion because at the intersection of road when car takes a turn its path is a part of circular motion in which the radius of the path is taken by the curvature of the path.
So here while taking the turn we can say that the force equation force the centripetal direction is given as
here we have
= Net centripetal force
so on increasing the value of speed the condition of over turning will increase
So above statement is TRUE
Answer:
3- kinetic energy was transferred from the water to the ice
Explanation:
the kinetic energy in this situation is the molecules vibrating so the molecules in the ice absorb it and make the molecules not vibrate so it gets colder
