What is the specific heat capacity of dry hops?
The specific heat capacity of dry hops can vary depending on their moisture content and variety. On average, dry hops have a specific heat capacity of around 2.0 J/g°C.
What is the importance of wiping the ice dry before introducing it to the water in the calorimeter and how would it affect the outcome of the experiment?
The specific heat of water is different from the specific heat of ice and so 'wet ice' into a calorimeter experiment can increase the mass of water in the calorimeter and become a source of unaccuracy.
Is specific latent heat of ice is same for water or not?
The specific latent heat of ice and water is not the same. The specific latent heat of fusion for ice (the heat required to convert ice to water at 0°C) is approximately 334 kJ/kg, while the specific latent heat of vaporization for water (the heat required to convert water to vapor at 100°C) is significantly higher, around 2260 kJ/kg. Thus, the energy required for phase changes differs between ice and water.
Does dry ice keep things cold?
Yes, dry ice can keep things cold because it sublimates, meaning it turns directly from a solid to a gas without becoming a liquid. This process absorbs heat from its surroundings, keeping things cold.
What happens to dry ice is heated?
If you heat dry ice, it turns in to CO2 gas. This is easily seen when you put dry ice in to hot water. You see tons of tiny CO2 gas bubbles popping up.
What is dry ice specific heat?
The specific heat of dry ice, also known as solid carbon dioxide, is approximately 0.82 joules per gram degree Celsius (J/g°C). This means that it takes 0.82 joules of energy to raise the temperature of 1 gram of dry ice by 1 degree Celsius.
Why does dry ice evaporate faster than a regular ice cube?
Dry ice is frozen carbon dioxide, totally different from ordinary ice, which is frozen water. Dry ice is much colder than water ice, thus evaporates quicker at room temperature. DO NOT TOUCH DRY ICE! It can hurt you badly.
Which turns into a gas faster dry ice on a paper towel or dry ice in water?
dry ice is (i don't remember ) minus 80? Celsius degrees and it turns to gas because of heatsince air is heat-isolating and water is heat-leading the answer is dry ice in water

Why does dry ice sublimate so fast in water?
Dry ice sublimates so rapidly in water because the temperature difference causes the solid carbon dioxide to transition directly into a gas, creating bubbles and further accelerating the process. Additionally, the interaction between the dry ice and the water causes agitation, which helps break down the dry ice into gas more quickly.
Why does things freeze in dry ice?
Things freeze in dry ice because dry ice is solid carbon dioxide that is extremely cold at -78.5°C (-109.3°F). When an object comes into contact with dry ice, heat is transferred from the object to the dry ice, causing the object's temperature to drop rapidly and freeze.
What happen if you heat dry ice to 50C?
Frozen carbon dioxide (dry ice) will turn back to a gas when heated at any temperature above freezing.
Is specific latent heat of ice is same for water or not?
The specific latent heat of ice and water is not the same. The specific latent heat of fusion for ice (the heat required to convert ice to water at 0°C) is approximately 334 kJ/kg, while the specific latent heat of vaporization for water (the heat required to convert water to vapor at 100°C) is significantly higher, around 2260 kJ/kg. Thus, the energy required for phase changes differs between ice and water.
How much heat is necessary to vaporize 500 grams of ice at its freezing point?
The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
What is the specific heat of ice?
0.5 calories/gram
Is dry ice exothermic?
Dry ice sublimation (changing from solid to gas) is an endothermic process because it requires heat energy to break the intermolecular forces holding the solid together. However, when dry ice sublimates in an enclosed space, it can release cold temperatures and feel cold to the touch, but this is due to the removal of heat energy from the surrounding environment, not due to an exothermic reaction.
