Its like water. Can you smell water? NO! So the cold things have ice on them, and the ice is made of water. You can't smell it. You can't smell boiling water either, so that argument doesn't hold.
Other things smell when its cold like petrol (gasoline).
Answer
When things are heated the molecules vibrate more rapidly, some molecules may gain enough energy the become a gas, but not all of them or your chocolate bar would evaporate! The gas molecules can diffuse through the air and up your nose where they can be sensed by chemical receptors. This makes cooking food that is very hot smell great.
If the object is cold the molecules will have less energy and fewer will become gaseous meaning fewer molecules reach your chemical receptors so the object will be harder to smell. Therefore you can't smell frozen foods very well at all.
Some molecules evaporate very easily such as petrol molecules, this means that you can smell them even though it is cold. Many molecules we just arn't very good at sensing, like water and oxygen, I guess we just don't have the correct chemical receptors. Imagine if we could smell how humid the day was for example, it would be a pain really and take a lot of brain power.

Why do hot beakers crack in cold wale?
im assuming you meant to type water... this happens because heat makes things expand, whilst cold makes things contract. by putting a hot beaker in cold water, you put too much strain on the beaker because it is changing size so fast

Why does a hot food has a stronger smell than cold food?
Smell is the vibration of the etheric body. On heating they expand. Therefore it is better to eat meat and fish cold.
Why cant you smell cold food from far while you can smell hot food from far?
It is possible to smell food when it is cold. However, it is much easier to smell food when it is hot. The heat gives off thermal energy, which makes it simpler to smell. Because hot food is much simpler to smell, hotter food often tastes better than colder food. If a food smells good to someone, then it often has a better taste, too. Edit: If the cold food has spice on it, then yes! Or if it has garlic in it!
Why is a cool bag suitable to keep hot things hot and cold things cold?
Hot things get cooler, and cold things get warmer, because they exchange heat with their surroundings. A "cool bag", whatever that is, is apparently designed in such a way as to prevent that (probably it's insulated).
What tells you how cold or hot things are?
a thermometer
Why do things shrink when it is cold?
Because most things, such as metals, expand when hot. So cold does the opposite.
Why did you lose your taste buds after a cold?
Smell is a large part of taste. If you can't smell, things will taste differently.
What has more energy something hot or something cold?
Hot things have more energy than cold one.
The smell of hot sizzling food reaches you several metres away but to get the smell from cold food we have to go closewhy?
Particles of matter are continuously moving. They possess the kinetic energy. As the temperature rises, particles move faster. Thus, particles that carry smell of hot sizzling food move faster than the smell of the cold food. Therefore, the smell of hot sizzling food can reach us several metres away, but to get smell from a cold food you have to go close.
Is 353 degree celsius hot or cold?
It is too hot for living things.
