Which if starting at the same temperature will cool slower on a hot day potato watermelon bread or dried beans?

The watermelon will cool the slowest for two reasons:
- it has the greater volume relative to the surface area (surface area increase with the square of dimensions while volume increases with the cube of dimension) so there is less surface area per unit mass and heat transfer is proportional to surface area
- since it contains more water than the others and water has a high heat capacity, it will take more energy to cool the same mass of watermelon than it would to cool the others

What is the effect of temperature on water?
the effect of temperature on water is that when the temperature increases the water particles move faster and when moove too fast the water evaporates. but when the temperature decreases, the particles move slower, creating no heat and the water freezes. (:
What is the reason of pendulum clocks become slow in summer?
During the summer the pendulum which is generally made of metal, expands due to the rise in temperature. this causes the pendulum to move slower and hence the clock becomes slower.
Why does a hot cup cool down more quickly from 80degrees-60degrees than 60degrees-40degrees?
Since temperature falls off exponentially, the temperature falls quickly initially and then at a slower rate.
Why rubber bands are affected by temperature?
the colder the rubber bands are the slower themolecules move and the more heated up they are the raster they move!!!!!!!!!!!!!!PS. i I'm a kid
When the temperature of a substance is lowered its particles?
slower i think cos isn't it the energy that makes the particles move in the first place? I'm not completely sure tho
Why do potatoes last longer in the refrigerator?
Because there kept fresher in the refrigerator The enzymes in the microbes that eventually cause fungal growth within the potato are below the optimum temperature neded to work. This means when compared to room tepmerature (which is closer to their optimum temp) they work slower and therefore reproducing the 'bad stuff' in the potato that causes it to go rotten slower.
When salt is added to boiling water at 100 degrees Celsius will the water boil faster or slower?
Slower, at higher temperature that is.
Can heat make a crystal grow slower or faster?
It depends on the type of element/compound(s) you are working with, the composition of the system and the starting temperature and pressure etc etc etc. The simple answer is both.
Do particles in a liquid move faster or slower when the temperature increases?
faster
What happens to enthalpy when temperature is decreased?
the atoms (or molecules) within the substance move slower, as temperature decreases.
Does water or land reach a higher temperature?
Water (oceans) is slower than land to warm up, and also slower to cool down.
What do you think happens to a fish's behavior in cold climate during the winter?
The colder the temperature, the colder the water temperature. The colder the temperature, the slower the fish's metabolism. The slower the fish's metabolism, the more sluggish and slow the fish is. The fish will have less energy and some fish even hibernate.
How does temperature affect decomposition of flesh?
hot decomposes fast and cold decomposes slower
How does a liquid evaporates and freezes?
In matter, atoms are constantly moving, but the speed at which they are moving influences their form. Faster moving atoms are a gas, slower than that is a liquid, and even slower than that is a solid. The colder the temperature, the slower atoms move. As the temperature gets closer to freezing temperature, the atoms slow down in moving more and more. Thus the liquid becomes a solid. *FYI - The fourth form of matter is Plasma
Which melts the regular ice slower?
This depends on the amount of salt, the ambiental temperature, the structure of ice.
Do the temperature affect the rate of evaporation?
Yes the hotter the weather the faster the evaporation, the colder the slower
Can you estimate temperature using cricket chirps sometimes?
yes the slower the hotter the faster the colder
