On a hot day, the density of the air will be less than that of the cold day since the low presence of moisture/ suspended water particles. Smoke is a stream of suspended partcles having sizes in a very few microns. When they get discharged into air in a hot day, due to low density of air at that time they try to flyaway.
In warmer water, particles generally have more energy. This makes them move faster, and so spread out faster.
Germs do breed faster in warmer climates. However, swine flu is just as likely to spread in summer as it is in winter.
the tar and the other chemicals in the smoke can spread because hot airs spread. So when someone smokes and you get close to them and breathe in the air, you could get the cancer the smoker could get.
Aroma molecules travel faster in hot air because the heat causes the molecules to move more rapidly and spread out faster. In cold air, the molecules move slower and spread more slowly, resulting in a slower dispersion of the aroma.
Ants do indeed run faster on hot days. They do this to get to their nest quicker because they use their body heat to warm up the nest for the night.
I wouln't recomemd it as hot dogs are meat and bacteria spread faster in meat! ☺
The hypothesis would be that food coloring will spread faster in hot water compared to cold water due to higher temperature increasing molecular movement and diffusion rates.
If you pour it in a saucer, it will spread out and there is less surface area and it cools faster.
The molecules start moving faster and spread out, meaning that the air is warm/hot.
Food coloring will spread faster in hot water than in cold water. The higher temperature in hot water increases the kinetic energy of the water molecules, leading to more rapid movement and diffusion of the food coloring throughout the liquid. In contrast, cold water has slower-moving molecules, which results in a slower spread of the coloring.
A football will typically travel faster in hot weather compared to cold weather. This is because the air molecules are more spread out in hot weather, reducing air resistance and allowing the ball to move more quickly through the air.
If you have the same volume of both then there are in cold water more molecules.
