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

How could a sample of water be tested to see if it is pure?Find out the boiling point of the sample, if the sample is pure the boiling point will be above and/or below 100 °C.Find out the volume of the sample, if the sample is pure the volume will be at a fixed point.Find out the volume of the sample, if the sample is pure the volume will be over a range of values.Find out the boiling point of the sample, if the sample is pure the boiling point will be at 100 °C precisely.

state the physical property which varies with temperature in a liquid glass thermometer

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)

If a liquid is at its exact boiling point, what will happen to the liquid when a small amount of heat is added to it?A.None of the liquid will turn to gas, and the temperature will increase.B.All the liquid will turn to gas, and the temperature will remain the same.C.A small amount of the liquid will turn to gas, and the temperature will increase.D.A small amount of the liquid will turn to gas, and the temperature will remain the same.

The normal boiling point of a liquid isQuestion 6Select one:the temperature at which the gas molecules have more kinetic energy than the molecules in the liquid.the temperature above which the substance cannot exist as a liquid regardless of the pressure.the temperature at which the liquid will usually boil.the temperature at which the vapour pressure equals 101.3 kPathe only temperature at which there can be equilibrium between liquid and gas.
