Which one is not a mixture? a) Tap water b) Air c) Chlorine gas d) Mix green salad 37. Which method of heat transfer involves solids? a) conduction b) convection c) radiation

Explanation / Answer

31) b) celsius and kelvin

the difference of freezing point and boiling point of water is 100.

32) water

at 4 deg.celsius water has highest density, that means lowest volume, if we heat or cool, water start to expand

33) momentum

all other three are a method of heat transfer, momentum is the product of mass and velocity.

34)entropy

entropy is a measure of the energy dispersal at a particular temperature.

35) nitrogen

air contains 78% nitrogen and 21% oxygen and 0.93% argon.

36)chlorine gas

37)conduction

in solids heat transfer to the adjacent atoms, or molecules.
