Answer:

- 130.64°C.

Explanation:

  • We can use the general law of ideal gas:<em> PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

  • If n and P are constant, and have two different values of V and T:

<em>V₁T₂ = V₂T₁</em>

<em></em>

V₁ = 634.0 L, T₁ = 21.0°C + 273 = 294.0 K.

V₂ = 307.0 L, T₂ = ??? K.

<em>∴ T₂ = V₂T₁/V₁ </em>= (307.0 L)(294.0 K)/(634.0 L) = <em>142.36 K.</em>

<em>∴ T₂(°C) = 142.36 K - 273 = - 130.64°C.</em>

(BEST ANSWER FOR BRAINLIEST)
tekilochka [14]

Answer: The faster stuff or an object moves, the more energy it has. ... Energy can be transformed from one way to another. Kinetic energy can be told apart from the various forms of potential energy. A demonstration is:  toaster transforms electrical energy into thermal energy.

Explanation: An energy transformation is the change of energy from way to another. Energy transformations occur everywhere every second. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, and chemical. Because the law of conservation of energy states that energy is always conserved in the world and simply changes from one form to another, many energy transformations are taking place all the time
