What is the specific latent heat of fusion of mercury?
The specific latent heat of fusion of mercury is about 11.28 kJ/kg. This value represents the amount of energy required to change a unit mass of solid mercury at its melting point to liquid mercury at the same temperature, without changing its temperature.
What is an example of low specific heat?
An example of a substance with low specific heat is metal, such as iron or aluminum. These materials heat up quickly when exposed to heat and cool down quickly as well, due to their low specific heat capacity.
What substances that heat and cool quickly have a high or low specific heat?
A substance that has a low specific heat needs less heat to increase its temperature. In other words under a constant heat flux it will heat or cool more quickly than the higher specific heat substances.
Will things that heat quickly have a low or high specific heat?
Things that heat quickly typically have a low specific heat capacity, as they require less energy to raise their temperature compared to substances with a higher specific heat capacity.
What is a substance with low specific heat?
Substances with low specific heat have the ability to heat up or cool down quickly with a small amount of energy. Common examples include metals like copper and aluminum, which have low specific heat compared to substances like water.
What is the specific latent heat of fusion of mercury?
The specific latent heat of fusion of mercury is about 11.28 kJ/kg. This value represents the amount of energy required to change a unit mass of solid mercury at its melting point to liquid mercury at the same temperature, without changing its temperature.
What are the advantages of mercury as a thermometeric liquid?
As mercury has a low specific heat yet is a good conductor of heat it has been the choice for thermometers. The ease of reading is due to the fact that the mercury does not wet the walls of the glass.
What is an example of low specific heat?
An example of a substance with low specific heat is metal, such as iron or aluminum. These materials heat up quickly when exposed to heat and cool down quickly as well, due to their low specific heat capacity.
Mercury has one of the lowest specific heats This fact added to its liquid state at most atmospheric temperatures makes it effective for use in thermometers If 257 J of energy are added to 0.450 kg?
The specific heat of a substance is the amount of energy needed to raise the temperature of 1 kg of that substance by 1 degree Celsius. Because mercury has a low specific heat, it heats up quickly when energy is added to it. In this case, 257 J of energy added to 0.450 kg of mercury would cause a significant temperature increase due to its low specific heat.
What substances that heat and cool quickly have a high or low specific heat?
A substance that has a low specific heat needs less heat to increase its temperature. In other words under a constant heat flux it will heat or cool more quickly than the higher specific heat substances.
Will things that heat quickly have a low or high specific heat?
Things that heat quickly typically have a low specific heat capacity, as they require less energy to raise their temperature compared to substances with a higher specific heat capacity.
Water has a relatively low specific heat?
The specific heat of water is high. An example of an object with low specific heat would be a metal pan. Since specific heat is the energy needed to raise 1g of something 1 degree Celsius, water would have a high specific heat.
Is desert sand a high or low specific heat capacity?
The desert sand has very low specific heat because it absorbs and releases heat very readily.
What is a substance with low specific heat?
Substances with low specific heat have the ability to heat up or cool down quickly with a small amount of energy. Common examples include metals like copper and aluminum, which have low specific heat compared to substances like water.
How does the specific heat affect the cooling and heating of materials?
The specific heat of a material determines how much heat energy is needed to change its temperature. Materials with high specific heat require more energy to heat up or cool down compared to materials with low specific heat. This means materials with high specific heat will heat and cool more slowly than those with low specific heat.
Does sand have a high or low specific heat capacity?
Sand has a relatively low specific heat capacity compared to other substances. This means that it heats up and cools down quickly when exposed to temperature changes.
Does a substance that heats up have a high or a low specific heat capacity?
A substance that heats up quickly has a low specific heat capacity, while a substance that heats up slowly has a high specific heat capacity. This is because substances with high specific heat capacities require more energy to change temperature compared to substances with low specific heat capacities.
