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.
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 are the applications of latent heat of fusion and latent heat of vapourisation?
the application of latent heat fo fussion is ice is used to put in drinks to make cool because ice has hih specific heat capcity
How are specific heat of water and ice the same?
That is how specific heat is defined. When you measure something you have to measure it relative to some point of reference. In specific heat it was agreed upon that water was to be the standard and its specific heat would be one. Therefore everything else is measured relative to water.
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 solid carbon dioxide is 54,55 J/mol.K at -83,37 oC.
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.
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.
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.
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.
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.
