Science what do you use for heating small amounts of liquid?
Generally you'd use a heat block.
If a susbtance has a high heat of vaporization what does this mean in terms of the quality of heat needed for the evaporation of this liquid?
It's not the quality of the heat, but the quantity of the heat. It means you need to put a large amount of (heat) energy into that substance to convert it from liquid to vapor at the same temperature. (Check out boiling water.)
How is the Hfusion used to calculate the energy required to vaporize a volume of liquid?
Liters liquid 1000ml/1L g/ml mol/g Hfusion
Which liquid would be most difficult to raise or lower the temp of?
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
How long does it take thick liquid to boil?
It depends on the liquid, water is 100 Celsius. --------------- Everything is a little confused here. Solids are not liquids. If you are asking about time, you would have numerous additional factors to consider. The substance The boiling point. The starting temperature Quantity of the substance Amount of heat being applied, and even the maximum amount of heat that your heat source is capable of applying. Perhaps also insulation. An electric arc might be able to essentially vaporize a small amount of metal almost instantly. Consider an ancient flash bulb, or what happens when you connect too much power to an automobile fuse. Likewise, it takes very little effort to make liquid nitrogen boil.
What would you use to heat small amount of liquid?
A Bunsen Burner
When a given quantity of a liquid is heated the mass quantity will vary and how?
The volume will increase, since most liquids tend to expand when they are heated. The mass will NOT increase, for most practical purposes - since there is something called "conservation of mass". However, the energy added to the liquid is equivalent to a small amount of mass; this is insignificant for most practical purposes.
How do you determine specific heat capacity of a liquid?
To determine the specific heat capacity of a liquid, you can use a calorimeter. By measuring the initial and final temperatures of the liquid when it absorbs a known quantity of heat, you can calculate the specific heat capacity using the formula Q = mcΔT, where Q is the heat absorbed, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the change in temperature.
What would temperature of a liquid at a temperature of degrees C and of specific gravity of 0.7 be after the addition of 13521600 Jules of energy?
To calculate the final temperature of the liquid after adding the energy, we would need more information such as the specific heat capacity of the liquid. The change in temperature can be calculated using the formula Q = mcΔT, where Q is the energy added, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the change in temperature. Once these values are known, we can determine the final temperature of the liquid.
How do you work out the quantity of heat?
by dividing the quantity of heat of a substance by the mass of that substance

How does the amount of heat required to change water from a solid to a liquid compare with the amount needed to change from a liquid to a gas?
Very simply, the amount of heat required to change state is exactly the same for solid to liquid (ice to water) and liquid to gas (water to steam) for a given substance, in this case water. The basic measurement of heat is the BTU (British Thermal Unit). 1 BTU is the quantity of heat required to raise 1 pound of water 1 degree Fahrenheit at atmospheric pressure. Keep in mind that there are two 'types' of heat to consider when contemplating the change of state of a substance: Sensible heat and latent heat. Clearly, sensible heat we can measure directly with a thermometer. Latent heat is a calculated quantity. When water undergoes the change of state from water to steam (liquid to gas) it does so through the gain of heat quantity. That heat gain that causes the change of state is latent heat, i.e; the actual heat gain is unmeasurable by thermometer since the temperature of that water is 212 deg f as it undergoes the change of state to steam, and that steam is also 212 deg f. Any increase in the temperature of the steam is said to 'superheat' the steam. As an example, steam fed boilers are nearly always supplied with 'superheated' steam at temperatures near 600 deg f. We see the addition of heat quantity as sensible heat during the rise of the waters temperature to 212 deg f (we are able to measure the rise in temperature), then we see the addition of heat quantity as latent heat during the change of state to gas from liquid (no change in the measurable temperature during the change of state), and again the addition of heat quantity as sensible heat in the process of 'superheating' the steam to any temperature above 212 deg f. If you can quantify the amount of water in pounds, you can quantify the amount of heat in BTU's.
What happen to liquid when it absorbs or released heat?
Liquid would get changed into gas form at this fixed temperature, called as Boiling point of the liquid. The heat thus given will be known as Latent Heat.
What is the heat of evaporation?
The heat of evaporation, also known as latent heat of vaporization, is the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the liquid together.
Is heat transfer a scalar quantity or vector quantity?
A vector
Would you add heat or take away heat to freeze a liquid?
Freezing is an exothermic process.
If a susbtance has a high heat of vaporization what does this mean in terms of the quality of heat needed for the evaporation of this liquid?
It's not the quality of the heat, but the quantity of the heat. It means you need to put a large amount of (heat) energy into that substance to convert it from liquid to vapor at the same temperature. (Check out boiling water.)
