what is the pressure, in atmospheres, of 2.97 mol h2 gas if it has a volume of 73 liters when the temperature is 298 k? 0.50 atm
Triss [41]
P x V = n x R x T

P x 73 = 2.97 x 0.082 x 298

P x 73 = 72.57492

P = 72.57492 / 73

P = 1.0 atm

What happens to the potential energy of a book that is dropped from a desk to the floor?
Debora [2.8K]

Answer:

D.   It is converted into kinetic energy.

Explanation:

When a book is dropped from a desk to the floor, the potential energy of the book is converted to kinetic energy as it falls.

  • Potential energy of a body is the energy due to the position of the body.
  • At a particular height, the potential energy is maximum.
  • A body with mass and moving with velocity will have kinetic energy
  • As the book drops through the height, to conserve energy, the potential energy is converted to kinetic energy.
