A gas at 200 K occupies a volume of 350 ml. What temperature is needed to increase the volume
Rudik [331]

Answer: Temperature in constant pressure is 286 K

Explanation: If pressure remains constant, then V/T = constant.

V1 = 350 ml and T1 = 200 K and V2 = 500 ml.  V1/T1 = V2/T2

and T2 = T1· V2 / V1 = 200 K · 500 ml / 300 ml = 285,7 K

Caleb has a 860-kilogram car sitting in his back yard, gathering rust.
emmasim [6.3K]
<h3>Answer:</h3>

A. 860 kg

<h3>Explanation:</h3>

To answer the question we need to understand that;

  • Mass refers to the amount of matter in an object.
  • Weight, on the other hand, refers to the gravitational pull of an object to a given surface.
  • Mass is measured using a spring balance.

We also need to know that;

  • The mass of an object remains constant every where irrespective of the gravitational acceleration.
  • Therefore, an object on the surface of the earth would have the same mass as on the surface of the moon.
  • In this case; the mass of the car remains the same on the outer space as on the back yard.
