In A Rising Interest Rate Environment Bond Values Would Change Over Time Through

In a rising interest rate environment, bond values would change over time through many different ways. One way in which bond values would change involves the prices of the bonds themselves, when the interest rates decrease. In another manner, the prices of bonds would decrease when the interest rates increase. Inflation impacts the pricing of the bond because it directly affects its future cash flow. Due to the high risk of inflation, more and more investors would want a higher yield rate because of the associated risk.

Measures to manage risks include: shortening the time of maturity of the bonds to reduce any negative impact on the price of the bond. The longer the life-span of a bond, then there is an increase in the risk of interest rate that is associated with the bond. In order to maintain firm ground in the investment game, one must be wise in which bonds to invest. No one wants to lose money in investing on bonds that will cause more issues and losses than those that will be fruitful.

In A Sample Of Oxygen Gas At Room Temperature The Average Kinetic Energy Of All

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. Which postulate of kinetic molecular theory best explains how this is possible?

 Attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly.

 Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.

 Gases consist of a large number of small particles, with a lot of space between the particles.

 Gas particles are in constant, random motion, and higher kinetic energy means faster movement.
