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

What is the density of object A? Does it sink<br> or float in water?
Oksana_A [137]

Answer:

~1.5 g/cm3 and it does NOT float in water.

Explanation:

If you look at the graph, Object A weighs ~6 grams and is ~4 cm3 in volume

Density = Mass/Volume

So 6 grams/4 cm3 = 1.5 g/cm3

Water has a density of 1 g/cm3 and because Object A density is higher than that of water, it sinks.
