What else can I help you with?
Where should a thermometer be placed in a beaker?
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.
Why was it important not to let the thermometer rest on the bottom of the breaker?
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.
What are the properties of a beaker?
There are several properties that could help a person identify a beaker full of mysterious clear liquid. For example, smelling the liquid might help. Also, seeing what it reacts with, and where it falls on the pH scale would be helpful.
What state of matter is H2SO4?
At standard temperature (20C) and pressure, pure H2SO4 is in a liquid state.
Lisa had an unknown clear liquid in a beaker. After heating on a hot plate the liquid evaporated but a white solid was left inside the beaker. Based on Lisa's investigation the original clear liquid?
The original clear liquid was likely a solution containing a solid dissolved in a liquid. When heated, the liquid portion evaporated, leaving behind the solid component. This process is known as evaporation and is commonly used to separate mixtures of solids dissolved in liquids.
Why is it not allowed to let the bulb of the temperature touch the bottom nor sides of the beaker that contains your liquid measuring the temperature?
The bottom and sides of the beaker will be hotter than the liquid inside.
Why is it important to have the bulb of a thermometer submerged in liquid without touching the sides or bottom of the beaker?
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.

When a white powder is added to a liquid in a beaker at room temperature the beaker becomes too hot to touch What kind of reaction is this an example of?
Exothermic?

Taylor mixes two liquids together in a beaker. A solid forms at the bottom of the beaker and the liquid changes from pink to blue. Which of the following is true about the properties of the products?

What are the physical properties of chemicals?
It is liquid at room temperature.
What changes occur as you slowly heat a beaker of ice?
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.

What physical properties is bromine?
It is red in colour, and a liquid at room temperature
If a liquid is added to a beaker the pressure exerted by the liquid on the bottom of the beaker?
increases due to the increased weight of the liquid. This is because the liquid's weight creates a force that is spread out over the bottom of the beaker, leading to an increase in pressure.
What state of matter is H2SO4?
At standard temperature (20C) and pressure, pure H2SO4 is in a liquid state.
