Read the description below of a substance and an experiment on it. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can.The sample is 100.mL of a clear liquid. The density of the liquid is measured, and turns out to be 0.77/gmL. The liquid is then cooled in the refrigerator. At 10.0°C crystals begin to appear. The temperature of the liquid continues to decrease as more crystals form, until at 6.2°C the liquid is entirely solid.Is the sample made from a pure substance or a mixture?If the description of the substance and the outcome of the experiment isn't enough to decide, choose "can't decide."pure substancemixture(can't decide)

Kyle is gradually raising the temperature of a substance. He finds that it starts to melt at 113°C and has completely melted at 118°C. Is this a mixture or a pure substance?

Which of the following is TRUE about a pure substance?a.It is always a solid or gas.b.It can be an element.c.It does not have a fixed boiling point.d.It is also called "homogeneous mixture".

What do you mean by a pure substance?

A sample of a pure liquid is heated in a glass beaker. The temperature at which the liquid just begins to boil willQuestion 6Select one:vary, depending on the pressure of the atmospherevary, depending on how rapidly the heat is supplied to the liquidalways be the same, because it is a pure substancevary, depending on the mass of the liquidvary, depending on the temperature of the room
