What is Q MLf?
Is dry ice poisonous?
If you mix dry ice with water, it will sublime—that is, change from a solid to a gas without existing in a liquid phase in between. If sublimation happens within an enclosed container, the carbon dioxide that’s produced will build up and this pressure will eventually cause a small explosion.
Once all the water has solidified, further removing energy reduces the temperature again. The key is that the process of freezing itself involves energy changes so instead of reducing the temperature, the energy comes from the conversion of liquid too solid.
The boiling point of water is 100 degrees Celsius. At this temperature the water will begin to change from the liquid state to the gas state. During the conversion process, temperature does not increase. It is, therefore, possible to have both liquid water and steam that exist at 100 degrees Celsius.
What is LF and LV in physics?
Q = MLf Eq. 1. where Q is the amount of heat absorbed by the solid, M is the mass of the solid that was melted and Lf is the latent heat of fusion for the type of material that was melted, which is measured in J/kg, NOTE: to fuse means to melt.
