Answer:
Being a noble gas, hrlium has a small molecular weight and it's chemical stability is high having the tendancy not to create chemical boudaries ( reactions)
Here I advice doing thought experiment and not remembering equations. By doing thought experiment you will write down equation by yourself.
Doing some work on a system means that system will "absorb" that energy. Here, system absorbs 1000J of energy. Now you are cooling system down by removing 500J of energy. That means that system will lose 500J of energy
All of that can be written as 1000 - 500 = 500 which means that after cooling your system has 500J left.
Responder:
20.3 ° C
Explicación:
<u>Según la ley de Charles</u>: <em>cuando la presión sobre una muestra de gas seco se mantiene constante, la temperatura y el volumen estarán en proporción directa.
</em>
Paso uno:
datos dados
Temperatura T1 = 20 ° C
Temperatura T2 =?
Volumen V1 = 12.2 cm ^ 3
Volumen V2 = 12.4 cm ^ 3
Aplicar la relación temperatura y volumen
sustituyendo tenemos
Cruz multiplicar tenemos
Temperatura delle braci 20.3°C
7 and a half hours because if you multiply 120 by 8 you get 960 and if you multiply 120 by 7 you get 840. So it’ll take 7 full hours and 30 minutes to reach 950 km. Hope this helps and I’m sorry if it’s wrong I did my best :)
