We apply the same amount of energy to 10.0-g samples of aluminum, iron, and silver which begin at the same temperature.
maw [93]

Answer:

Explanation:

A sound knowledge of specific heat capacity of the metals is required in this case.

The specific heat capacity of a metal is the quantity of heat required to the raise the temperature of a unit mass of it by 1°C.

It is related to quantity of heat using the expression below;

               H   =   m  c  Δt

where m is the mass

            c is the specific heat capacity

            Δt is the temperature change

let us make the specific the subject of the expression;

                     c  = \frac{H}{m x change in temperature}

we can see that there is an inverse relationship between specific heat and temperature change.

The specific heat capacity of a body is an intensive property that is unique to the metal.

   The higher the specific heat capacity, the lower the amount of temperature change in it.

Let us find the specific heat capacity of the given metals;

 Aluminium     0.897J/gK

 Iron                 0.412J/gK

 Silver               0.24J/gK

 After the heat is supplied,

      Silver >  Iron > Aluminium in terms of temperature change

Two gases are combined and sealed in a 2.0 L container. The 3.0 L of argon gas and 1.0 L of xenon gas each exert 1.00 atm pressu
mariarad [96]

Answer:

Unless they chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each individual gas in a mixture exerts the same pressure that it would exert if it were present alone in the container . The pressure exerted by each individual gas in a mixture is called its partial pressure.
