Answer: The correct answer is "greater thermal conductivity".
Explanation:
Thermal conductivity: It is a ability to conduct heat. Heat transfers occur at a lower rate to material at higher thermal conductivity.
It is defined as the rate at which the heat is transferred through a unit thickness of the substance per area per change in the temperature.
In the given problem, A piece of wood and a piece of steel are at the same temperature. However, the steel feels hotter. The thermal conductivity of the steel is more than the thermal conductivity of the wood.
Therefore, the correct option is "greater thermal conductivity".
B- Greater thermal conductivity
The type of change that has occurred on mixing ice cubes, water ,sugar, koolaid mix is a physical change.
Physical changes are defined as those changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to further simpler compounds.
Physical changes are always reversible by using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible changes and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.
