Bella observes that the gas-filled tire of her bicycle becomes a little deflated when she keeps the bicycle outside in cold weat

her. Which of the following laws is used to understand the behavior of the gas and why? The low temperature outside lowers the volume of the gas according to Charles's law because this law describes how a gas will behave at constant pressure. The low temperature outside increases the volume of the gas according to Charles's law because this law describes how a gas will behave at constant pressure. The low temperature outside lowers the volume of the gas according to Boyle's law because this law describes how a gas will behave when the number of moles remains constant. The low temperature outside increases the volume of the gas according to Boyle's law because this law describes how a gas will behave when the number of moles remains constant.

The low temperature outside lowers the volume of the gas according to Charles' law because this law describes how a gas will behave at constant pressure. It shows that the volume of a given mass of a gas is directly proportional to the absolute temperature provided the pressure remains constant. An increase in temperature leads to an increase in volume while a decrease reduces the volume. This is due to the reduction in the distances traveled by the vibrating  particles of the gas because of the lost kinetic energy.

Answer:

.079 moles of Nirogen gas (N2)

Explanation:

You can see from the equaton that each ONE mole of N2 produces TWO moles of NH3.

 Find the number of moles of NH3 produced.

    Using Periodic Table : Mole wt of NH3 = 17 gm/mole

          2.7 gm / 17 gm/mole = .1588 moles

      One half as many moles of N2 are needed  = .079 moles

1/2 * m * v ^ 2 = mgh
viktelen [127]

C. the square root of 2gh

Explanation:

The square root of 2gh is equivalent to Torricelli's law in the equation.

  given expression:

         \frac{1}{2} m v² = mgh

 to find v, we make it the subject of the expression:

    *multiply both sides of the equation by 2:

             

                     2 x( \frac{1}{2} m v² )= 2 (mgh)

                                      mv²  = 2mgh

    *cancel the mass, m appearing on both sides:

                                    v²  = 2gh

  * find the square root of both side

                                     v = √2gh
