Why does dry ice sublimate so fast in water?
Dry ice sublimates quickly in water because water is both relatively dense and has a high specific heat, which means that a relatively small volume of it can transfer a larger amount of heat.
What is the importance of wiping the ice before introducing it to the water in the calorimeter?
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.
To keep dry ice from forming a gas what needs to happen?
Remove heat energy - it will limit the movement of particles, keeping more dry ice in the solid state.
Is dry ice a element?
Dry ice is not an element. Dry ice is solid carbon dioxide, CO2, which is a compound.
Does ice melt faster in water or alcohol?
Assuming they are the same temperature, the ice will melt faster in water, due to water's high specific heat.

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
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.
What is the specific heat of ice?
0.5 calories/gram
How did dry ice get its name?
It is called "dry" because when heat is given, it sublimes (turns from a solid into a gas). This is different from actual ice that turns from a solid to a liquid. It is called "ice" because solid carbon dioxide (dry ice) is very cold, similar to ice.
Does dry ice keep things cold?
No, dry ice is frozen Carbon Dioxide and will not heat up anything.its colder than ice so it would make it very cold
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 dry ice exothermic?
Dry ice is the cold dense white mist produced by solid carbon dioxide in the air. The sublimation of dry ice is an endothermic reaction.

How do you calculate the total heat required in kcal to take 70 grams of ice at -29.0 Celsius and convert it to steam at 106 Celsius?
heat energy required to raise the temperature of ice by 29 celsius =specific heat capacity of ice * temperature change *mass of ice + to change 1kg of ice at 0 celsius to water at 0 celsius =specific latent of fusion of ice*mass of water + heat energy required to raise the temperature of water by 106 celsius =specific heat capacity of water * temperature change *mass of ice + to change 1kg of water at 106 celsius to steam at 106 celsius =specific latent of fusion of ice*mass of steam
