Using a beaker, hot plate, and temperature probe, you can determine several properties of an unknown liquid. By heating the liquid and monitoring its temperature, you can identify its boiling point and melting point, which are critical for characterizing the substance. Additionally, you can observe changes in temperature over time to infer heat capacity and thermal conductivity. Other properties, such as viscosity and density, may also be assessed indirectly through observations of how the liquid behaves when heated.
Using a hot plate, temperature probe, and beaker, you can determine the boiling point and melting point of an unknown liquid. By heating the liquid gradually and monitoring the temperature, you can observe the temperature at which it changes from liquid to gas (boiling point) or solid to liquid (melting point). This information can help identify the liquid, as different substances have characteristic boiling and melting points. Additionally, you can assess the liquid's thermal conductivity and specific heat capacity through controlled heating experiments.
Yes, the properties of an unknown liquid can change before and after boiling. When the liquid reaches its boiling point, it undergoes a phase transition from liquid to vapor, which affects its physical properties such as temperature, density, and viscosity. Additionally, the composition of the liquid can change if any volatile components are released during boiling. However, the chemical identity of the liquid remains the same unless a chemical reaction occurs.
If she cools the content of the beaker, the temperature of the liquid will decrease, which may lead to a reduction in molecular movement. This often results in increased viscosity and potential condensation of gases if present. Additionally, if the liquid is a solution, cooling could cause solubility changes or precipitation of solutes. Overall, the physical properties of the contents will likely change as the temperature drops.
As you heat a beaker of ice, the ice will begin to melt and turn into liquid water. The temperature will slowly rise until it reaches a point where all the ice has melted. After that, the temperature will continue to rise as the liquid water heats up.
You must obtain and subtract the mass of the beaker.
The boiling point or melting point of an unknown liquid can be determined using a beaker, a hot plate, and a temperature probe. By heating the liquid and monitoring the temperature changes, you can identify the point at which the liquid boils or melts, which provides important information about its properties.

The bottom and sides of the beaker will be hotter than the liquid inside.

Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.

Exothermic?
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.

It is liquid at room temperature.
As you heat a beaker of ice, the ice will begin to melt and turn into liquid water. The temperature will slowly rise until it reaches a point where all the ice has melted. After that, the temperature will continue to rise as the liquid water heats up.
