Answer:

Explanation:
Let's use the equation that relate the temperatures and volumes of an adiabatic process in a ideal gas.
.
Now, let's use the ideal gas equation to the initial and the final state:

Let's recall that the term nR is a constant. That is why we can match these equations.
We can find a relation between the volumes of the initial and the final state.

Combining this equation with the first equation we have:


Now, we just need to solve this equation for T₂.

Let's assume the initial temperature and pressure as 25 °C = 298 K and 1 atm = 1.01 * 10⁵ Pa, in a normal conditions.
Here,
Finally, T2 will be:

Answer: Option (c) is the correct answer.
Explanation:
Language is defined as a medium through which a person can deliver its thoughts, ideas, or perceptions to one or more individuals.
For example, Leslie is feeling sad and that is why she is crying. Therefore, listening a cry sound her friend sitting in the next room came immediately to console her.
Hence, sound of crying is also a sign of language that tells Leslie is sad about something.
Therefore, we can conclude that the statement languages use spoken sounds, written words, and signs to represent ideas and events, is true about language.
Answer:
<em>In the case of a solar thermal panel we are trying to heat above the ambient temperature so conduction and convection will work against us by taking heat from the panel to the out- side world. ... The sun (at 6000 C surface temperature) is hotter than the solar panel so the panel will get hot due to the solar radiation.</em>
Explanation:
15.49 should be the answer if that is 12 watt battery.
I’m not sure sorry I really wish I could help
