The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system.
The thermodynamic variable defined by the zeroeth law is Temperature.

What is the first law of thermodynamics applied to closed and open system showing the meaning of the positive and negative sign of heat and work?
The first law of thermodynamics states that: "The internal energy of a system is a function of its state. Any increase in the internal energy of a system is equal to the sum of the heat supplied to the system and the work done on the system." In equations, this is stated as: DU = DQ + DW where DU is the INCREASE in internal energy DQ is the heat SUPPLIED DW is the work done ON the system So, if heat is lost by the system, it means that DQ is negative and if work is done by the system, it means that DW is negative. The best way to answer thermodynamics questions involving the first law is to think logically about what calculations should be made. If you do this, you will never make mistakes about signs.
Which choice best explains what internal energy is as it relates to the first law of thermodynamics?
Internal energy is the sum of the randomly distributed microscopic potential energy and kinetic energy of the molecules that make up the system. The first law of thermodynamics states that: "The internal energy of a system is a function of its state. Any increase in the internal energy of a system is equal to the sum of the heat supplied to the system and the work done on the system." The first law of thermodynamics is a direct consequence of the principle of conservation of energy.
How can fads lead to shortages?
Demand increases so quickly and unexpectedly that time is needed for the quantity supplied and price to increase to reach new equilibrium point
Why excess air is provided for combustion?
To ensure complete combustion of the fuel used, combustion chambers are supplied with excess air. Excess air increase the amount of oxygen and the probability of combustion of all fuel
What is the firs law of thermodynamic?
No acceleration means no force, a=F/m. The classical definition of the first law of motion is A body continues its state of rest or uniform motion unless and until it is acted upon by an external force.
What is The first law of Themodynamics?
* First law of thermodynamics, about the conservation of energy: : :: The change in the internal energy of a closed thermodynamic system is equal to the sum of the amount of heat energy supplied to the system and the work done on the system. --from Wikipedia

Can sound power a house with sound?
No. See the first law of thermodynamics, which states that the change in the internal energy of a closed thermodynamic system is equal to the sum of the amount of heat energy supplied to or removed from the system and the work done on or by the system or we can say " In an isolated system the heat is constant".

Why does a producer not increase quantity supplied in response to price increase?
Producers only increase quantity supplied in response to DEMAND increases. They only want to make as much as someone will buy.
What causes an increase in the quantity supplied?
