How does evaporation of different substances affect the temperature difference between the wet and dry thermometers?
Evaporation causes cools....it makes things cool and if you put a wet paper on a dry thermometer watch,Watch the temperature of the thermometer will drop extremely fast!! Try it at homee or school , anywhere, you'll love it<3 but make sure that the temperature of your house or school is warm and try not to open any windows or doors during the experiment!
Good Luck! :) Hope you like my Answer!<3 (well watever i got a level 4 when i told my teacher this information)*

What are Disadvantages of alcohol in glass thermometers?
Disadvantages of alcohol in glass thermometers include the risk of breakage and release of the toxic substance, potential for inaccurate readings due to alcohol evaporation or expansion/contraction, and the need for regular calibration to maintain accuracy. Additionally, alcohol thermometers are not suitable for high-temperature measurements.
What is the ethanol evaporation temperature and how does it affect the distillation process?
The evaporation temperature of ethanol is around 173.1F (78.37C). This temperature is important in the distillation process because it allows ethanol to vaporize and separate from other substances in the mixture. By heating the mixture to the evaporation temperature of ethanol, it can be collected as a separate, more concentrated liquid through condensation, leading to the purification of the ethanol.
What is the name of the process that changes a substance from a liquid to a gas at a temperature below the substances boiling point?
The process is called evaporation. It occurs when a substance changes from a liquid to a gas at a temperature below its boiling point, usually at the surface of the liquid.
Does acetic acid turn to gas at room temperature?
Acetic acid can evaporate and release vapors at room temperature. The rate of evaporation can be influenced by factors like temperature and air circulation. However, acetic acid does not have a high vapor pressure, so the evaporation process is slower compared to highly volatile substances.
What are the two substance used in liquid column thermometers?
iodine and Mercury

What is a thermo meter used for?
A thermometer is used to measure temperature in various environments or substances. It helps in monitoring body temperature, checking food temperatures for cooking, and gauging the temperature in industrial processes.
Energy that transfers between substances because of a temperature difference between the substances is known as .?
Heat.

What do thermometers actually detect about the moving particles that make up a sample of matter?
Thermometers actually detect the temperature of moving particles in motion. Both mercury and alcohol (substances in thermometers) grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold.

What two substances are used in the thermometer's glass tube?
Most commonly, the two substances used in a thermometer's glass tube are mercury and alcohol. Mercury is traditionally used in older thermometers, while alcohol (typically colored red) is used in modern thermometers as a safer alternative.
Why do Scientist use a thermometer?
Scientists use thermometers to measure temperature accurately in various scientific experiments and research. Temperature is a critical parameter that can affect chemical reactions, biological processes, and physical properties of substances. Thermometers help scientists to make precise measurements and analyze the impact of temperature on their study subjects.
Does the difference in the level of heat between two substances determine the heat transfer rate between the substances?
Yes, the greater the difference in temperature between two substances, the faster heat transfer will occur between them. This is because heat naturally flows from areas of high temperature to areas of low temperature in an attempt to reach equilibrium.
How miscible liquids can be sepearated?
Separation by destillation (evaporation / condensation) or freezing out (crystallisation at lower temperature). Both are not absolutely effective, no pure substances are obtained.
What abnormal substance will decrease due to evaporation?
The mass of all substances decrease by evaporation.
Can heat transfer occur when two substances are the same temperature?
No, heat transfer occurs due to a temperature difference between two substances. If both substances are at the same temperature, there is no temperature gradient to drive heat transfer, so no heat transfer will occur.
