First you can not add a cold temperature to anything. Ask your teacher to explain what heat is an what temperature is, because you clearly do not understand this. When a liquid BOILS - it turns into gas. When a liquid FREEZES - it turn into a solid.
The temperature. A liquid will increase in temperature until it reaches the boiling point temperature. At this temperature the liquid will become a gas. Under normal circumstances, the liquid cannot get any hotter than the boiling point without becoming a gas. So the liquid remains the same temperature until it has all boiled away.
Heat can make water boil, like when you put a pot of water on the stove on high!
Ice changes into water when some heat is involved. The heat energy is used as latent heat to change its state from solid to liquid but note that the temperature remains the same. This is can be seen by fixing an experimetn. Fill a beaker with ice and attach it with thermometer. Start heating it. Look at the temperature at the first and at the end when it is in liquid state. It remains same (0 degree celcius)
CO2 will not be a liquid at room temperature, rather a gas. It is only a liquid when compressed. Actually IF contained at high pressure it will be a liquid at room temperature ...It requires a combination of both pressure and temperature. It is a liquid in CO2 fire extinguishers and when the pressure is released some of it boils, absorbing a large amount of heat energy, more of it is released from the nozzle as a solid which then sublimes to forma gas.
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.
You're measuring the boiling point of the liquid.
a solid melts (and the liquid remains at the temperature of the solid).

A temperature at which internal pressure become equal to atmospheric pressure is called boiling pointAt boiling point kinetic energy of liquid molecules remains constant ,although heat is continously supplied that is why boiling point of a liquid remains constant.
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.

When heat is applied to a solid, its temperature rises until it reaches the melting point of the substance. As the heat application continues, the temperature remains constant at the melting point as all of the heat is consumed in changing the state of the substance from solid to liquid. It is only after the conversion to liquid is complete that the temperature of the substance again starts to rise as long as heat is still being applied.

The water will be require more water because it needs 80degrees more heat than the alchohol which only needs 50degrees more heat.
If you heat water its temperature will increase until it reaches 100 degrees C, at which point it starts to boil. Boiling means it is all changing into a gas. Whilst it is boiling, the temperature remains constant, because the energy is being used to separate the particles instead of making them move faster. Not until the liquid has become gas does the temperature rise again.
