Answer:
The expression is 
Explanation:
Generally smallest workdone done by a gas is mathematically represented as
Generally for an isothermal process
=> 
Generally the total workdone is mathematically represented as
=> 
=> ![nRT [lnV] | \left \ {V_f}} \atop {V_o}} \right.](https://tex.z-dn.net/?f=nRT%20%5BlnV%5D%20%20%20%7C%20%5Cleft%20%5C%20%7BV_f%7D%7D%20%5Catop%20%7BV_o%7D%7D%20%5Cright.)
=> ![W_c = nRT [ln(V_f) - ln(V_o)]](https://tex.z-dn.net/?f=W_c%20%3D%20nRT%20%5Bln%28V_f%29%20-%20ln%28V_o%29%5D)
=> 
From the question

Radiator. A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting/Ice melts because heat moves to the ice from the air
Answer:
E) a billion times brighter
Explanation:
- <u>The sun is a star, which is about billion times brighter as the reflected light from any planet orbiting around it. </u>
- The brightness is based on its composition and its position from the planet. The sun happens to be the brightest star on the Earth's sky which is about 13 billion times brighter than the next brightest star.
Answer:
upper part of any wave.
Explanation:
we normally define wave motion in term of movement of particles. compressions and rarefaction. rarefaction particles apart , and same as trough ( part of wave above mean line ).
The biosphere contains all the planet's living things. This sphere includes all of the microorganisms, plants, and animals of Earth. Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes. Deserts, grasslands, and tropical rainforests are three of the many types of biomes that exist within the biosphere.
The atmosphere contains all the air in Earth's system. It extends from less than 1 m below the planet's surface to more than 10,000 km above the planet's surface. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. When air temperature in the lower portion of this sphere changes, weather occurs. As air in the lower atmosphere is heated or cooled, it moves around the planet. The result can be as simple as a breeze or as complex as a tornado.
