Q1:which of the following best describes the relationshipbetween two systems in thermal equilibrium? is it A. no net energyis exchanged? B. the volumes are. Therefore thermal equilibrium is defined when energy is equally you are allowing swapping of particles between the two systems effectively. As we have seen in the zeroth law of thermodynamics, when two objects are The relationship between Joules and Calories is known as the Mechanical.
Temperature is also an intensive property, which means that the temperature doesn't change no matter how much of a substance you have as long as it is all at the same temperature!
On an atomic level, the molecules in each object are constantly in motion and colliding with each other.
Every time molecules collide, kinetic energy can be transferred. When the two systems are in contact, heat will be transferred through molecular collisions from the hotter system to the cooler system. The thermal energy will flow in that direction until the two objects are at the same temperature.
When the two systems in contact are at the same temperature, we say they are in thermal equilibrium. Zeroth law of thermodynamics: Defining thermal equilibrium The zeroth law of thermodynamics defines thermal equilibrium within an isolated system.
The zeroth law says when two objects at thermal equilibrium are in contact, there is no net heat transfer between the objects; therefore, they are the same temperature. Another way to state the zeroth law is to say that if two objects are both separately in thermal equilibrium with a third object, then they are in thermal equilibrium with each other.
The zeroth law allows us to measure the temperature of objects. Any time we use a thermometer, we are using the zeroth law of thermodynamics.

Let's say we are measuring the temperature of a water bath. The lymphatic system also transports lipids that are too large to be transported through the cardiovascular system via lacteals.
Describe the relationship between system call and system program? A system call is a routine which lies within the program itself to request a specific service from the OS kernel. Ms Word uses a system call routine to run spooler. Mind you, I'm not a programmer so that's the best I can do! Distinguish between thermal and mechanical equilibrium? Equilibrium means balance or equal.
Thermal equilibrium is when two systems have equal temperatures. Mechanical equilibrium is when two systems have equal pressure. In a steam… engine, if you stop putting fuel into the furnace, the pressure in the boiler will drop until it reaches mechanical equilibrium with the atmospheric pressure and the water will cool and reach thermal equilibrium with the ambient temperature.
The balance between pressure caused by heat and gravity caused bythe star's mass.
