Ryan takes three small cubes and places them on a glass plate. he leaves them for an hour at the room temperature (25*c).all but one change expected to occur after one hour. that is a change in the ice

a) mass
b) shape
c) temperature
d) physical state

The correct answer is D) Physical state

Explanation:

Water is converted to ice at 0 degree centigrade temperature. The physical state of ice is solid.

           When Ryan will place those three ice cubes on a glass plate for an hour at room temperature(25 degree centigrade) the entropy or randomness or disorder of molecules present in the ice will increase with increase in temperature.

        As a result after certain period of time(1 hour) the ice those were kept in the glass plate will start to melt into water.Thus the physical state of the ice will be changed.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
