A student sees a commercial that claims a new dishwasher is energy efficient.
erma4kov [3.2K]

Answer:

ENERGY STAR-certified dishwashers

Explanation:

use advanced technology to get dishes clean while using less water and energy. Soil sensors test the degree of dirt on dishes throughout the wash and adjust the cycle to achieve optimum cleaning with minimal water and energy use.

The first law of thermodynamics states that ΔE= Q− W . Is this also a statement of the principle of conservation of energy? Yes,
ozzi

Answer:

Yes, the heat that flows into the system is used to change the internal energy of the gas and becomes work done by the piston.

Explanation:

First law of thermodynamics known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.

The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics.

This is the first law of thermodynamics

ΔE= Q− W

ΔE= change internal energy of the system.

Q= heat transfer into the system

And

W= work done by the system.

Rewriting the equation

ΔE= Q− W

Q=ΔE +W

Show that the heat flowing l into the system is transferred to the internal energy of the system and the work done by the piston

So the third option is correct

How does a sound wave transfer energy to your ears ?
horrorfan [7]

Answer:

A. Particles in air move in circles as the wave moves forward.

B. Particles in air move forward but not backward as the wave moves

forward.

C. Particles in air move up and down as the wave moves forward.

✔ D. Particles in air move forward and backward as the wave moves

forward.

Explanation:

The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.
