When heat is applied gradually and evenly to solid ice at 0 Celsius, it melts. Does the temperature change while it is melting t
serious [3.7K]

No, the added heat melts the ice, but the result is water at the same temperature. Hence, option B is correct.

<h3>What is temperature?</h3>

The degree of hotness or coldness is measured on a definite scale.

Temperature doesn't change as heat is added during a phase change; for example, when the ice melts.

During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.

Thus, No, the added heat melts the ice, but the result is water at the same temperature.

Compare the volume of 14.1 g of helium to 14.1 g of argon gas (under identical conditions).
s2008m [1.1K]
The Volumes can be calculated from Masses by using following Formula,

                                        Density  =  Mass / Volume
Solving for Volume,
                                        Volume  =  Mass / Density

Mass of Both Gases  =  14.1 g

Density of Argon at S.T.P  =  1.784 g/L

Density of Helium at S.T.P  =  0.179 g/L

For Argon:
                                        Volume  =  14.1 g / 1.784 g/L

                                        Volume  =  7.90 L

For Helium:
                                        Volume  =  14.1 g / 0.179 g/L

                                        Volume  =  78.77 L
