It depends on the type of plastic being used. Hopefully the packaging label will let you know if it is intended for liquids, solids, hot, or cold. If you don't have that information, you should test it first. The same considerations apply to plastic spoons. Some spoons turn soft and collapse when in boiling water.
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
Measuring the temperature of the boiling point at different pressures.
Boiling water in a plastic bag can be unsafe because the high temperature can cause the plastic to release harmful chemicals into the water. It is recommended to use containers specifically designed for boiling water to ensure safety.
When ethylene glycol is added to water, the boiling point of the resulting solution increases. Ethylene glycol acts as an antifreeze, raising the boiling point and lowering the freezing point of water.
Any added impurity can change the boiling point of a liquid.
The fixed points on the Celsius scale, for measuring temperature are based on the freezing and boiling points of water and, to that extent water is relevant to the measurement of temperature.
It is generally not safe to use plastic containers for boiling water as they can release harmful chemicals when exposed to high temperatures. It is recommended to use containers made of heat-resistant materials such as glass or stainless steel for boiling water.
It is not advisable to pour boiling water in a plastic bottle. It can cause skin burns if it spills on you. And the plastic bottle could melt or shrink! Wait until the water has cooled off before transferring it into plastic.
What did you observe! This is not a question we can answer as we were not present when the salt was added.
Ethanol is a better solvent for boiling point elevation compared to water. This is because ethanol has a higher boiling point than water. When a solute is added to ethanol, it will raise the boiling point of the solution more significantly than if the same solute were added to water.
Clinical thermometers are not used to measure the temperature of boiling water! They have a range of about 35oC to 43oC and they will explode at a temperature of about 100oC! Ordinary laboratory thermometers are used.
