Which has more kinetic energy the molecules in a gram of ice or the molecules in a gram of steam?

51. Which has more kinetic energy: a molecule in a gram of ice water or a molecule in a gram of steam? A molecule in a gram of team has considerably more kinetic energy, as evidenced by its higher temperature. Iceberg has more internal energy.

Why will a watermelon stay cool for a longer time than sandwiches?

Why does a piece of watermelon stay cool for a longer time than sandwiches do when both are removed from a picnic cooler on a hot day? Sample Answer: Water in the melon has more “thermal inertia” — a higher specific heat than sandwich ingredients.

Which warms faster when heat is applied iron or silver which has the lower specific heat capacity?

Which warms up fastest when heat is applied: water, iron, or silver? Silver warms up faster than iron.

Does iron or silver heat up faster?

Thus if same amount of heat is given to both, then iron warms up faster than silver.

Why can you walk on red hot coals without getting your feet burned?

The coals are not good conductors of heat. Why is one able to walk on red-hot coals without getting one’s feet burned? The coals are neither very hot, nor are they good conductors of heat.

What evidence can you cite for the claim that water can boil at a temperature of 0 C?

Evidence that water can boil at a temperature of 0°C? Ice will form in boiling water in a vacuum chamber. Pressure is greatly reduced, water starts to boil. Continued boiling results in lowered temperature, and lower boiling point.

When the temperature of ice cold water is increased slightly does it undergo a net expansion?

Liquids generally expand more with an increase in temperature. 24. When the temperature of ice-cold water is increased slightly, does it undergo a new expansion or a net contraction? When the temperature of ice cold water is increased slightly, it undergoes a net expansion up to 4C.

What is the reason for ice being less dense?

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Which generally expands more for increases in temperature?

In general, liquids will expand more than solids with an equal increase in temperature. Similarly, in general, gases will expand more than liquids with an equal increase in temperature.

Does metal expand with heat?

Metal expands when heated. Length, surface area and volume will increase with temperature. The scientific term for this is thermal expansion. The degree of thermal expansion varies with different types of metal.

Which is an example of anomalous Behaviour of water?

Dew point
