What is the specific heat of alcohol and how does it affect its ability to absorb and release heat compared to other substances?
The specific heat of alcohol is about 2.44 J/gC. This means that alcohol can absorb and release heat more efficiently compared to other substances with lower specific heat values. This property allows alcohol to heat up and cool down faster, making it useful in applications where quick temperature changes are needed.

What is the specific heat of alcohol and how does it compare to other substances?
The specific heat of alcohol is around 2.44 J/gC, which is lower than water but higher than most other substances. This means that alcohol requires less energy to change its temperature compared to water, but more than many other materials.
Do alcohols have higher boiling points compared to other substances?
Yes, alcohols generally have higher boiling points compared to other substances due to the presence of hydrogen bonding between alcohol molecules.
Is acetone stronger than alcohol in terms of its solvent properties?
Acetone is generally considered to be a stronger solvent than alcohol due to its ability to dissolve a wider range of substances.
Is rubbing alcohol a mineral?
No, rubbing alcohol is not a mineral. Rubbing alcohol is a liquid solution made up of isopropyl alcohol and water. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure.
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 substances is NOT stimulant?
Substances that are not stimulants include depressants (such as alcohol and benzodiazepines) and hallucinogens (such as LSD and psilocybin). These substances work on the central nervous system in different ways compared to stimulants.
Do alcohols have higher boiling points compared to other substances?
Yes, alcohols generally have higher boiling points compared to other substances due to the presence of hydrogen bonding between alcohol molecules.
Is alcohol a surfactant?
Yes, alcohol can act as a surfactant, particularly when it comes to its ability to reduce surface tension and stabilize emulsions. In solutions, alcohol molecules can interact with both water and oil, allowing for better mixing of these typically immiscible substances. However, the surfactant properties of alcohol are generally weaker compared to traditional surfactants like soaps and detergents.
Why isn't alcohol a good solvent?
Alcohol is not considered a good solvent for many substances because it has a relatively low dielectric constant, which limits its ability to dissolve ionic compounds effectively. Additionally, while alcohol can dissolve polar compounds due to its hydroxyl group, it is less effective for nonpolar substances compared to organic solvents like hydrocarbons. Furthermore, the hydrogen bonding in alcohols can lead to solvation effects that might hinder the dissolution of some solutes.

Is acetone stronger than alcohol in terms of its solvent properties?
Acetone is generally considered to be a stronger solvent than alcohol due to its ability to dissolve a wider range of substances.
Is there oil in 91 percent Isopropyl alcohol?
No, Isopropyl alcohol does not contain oil. It is a type of alcohol that is typically used as a solvent or cleaning agent due to its ability to dissolve substances like oils, so it is oil-free.
Can alcohol mix with water?
Yes, alcohol can mix with water. When both substances are combined, they form a homogeneous solution. The ability of alcohol to mix with water is due to their similar polar nature.
Is rubbing alcohol a mineral?
No, rubbing alcohol is not a mineral. Rubbing alcohol is a liquid solution made up of isopropyl alcohol and water. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure.
Does water or rubbing alcohol dissolve the fastest?
Rubbing alcohol typically dissolves faster than water due to its lower surface tension and ability to break down substances more easily.
How does alcohol effect specific gravity?
Alcohol lowers the specific gravity of a liquid because it is less dense than water. When alcohol is mixed with water, the overall density of the mixture decreases, resulting in a lower specific gravity compared to pure water. This property is often utilized in brewing and winemaking to determine alcohol content, as higher alcohol levels correspond to lower specific gravity readings.
