Question

What is your test version? A B C D The figure shows three linear temperature scales with freezing and boiling points of water indicated. Which of the following corresponds to the greatest change in temperature? All of these 25 R degree 25 S degree 25 U degree Which of the following best explains why water in a lake freezes from the top down? From 0 degree C to 4 degree C, water has a negative coefficient of volume expansion. From 0 degree C to 4 degree C, water has a positive thermal conductivity. From 0 degree C to 4 degree C, water has a negative thermal conductivity. Water has a relatively large specific heat. From 0 degree C to 4 degree C, water has a positive coefficient of volume expansion. On Earth, solar energy is harnessed through which type of heat transfer? Induction Conduction Convection Radiation Polarization A sealed, fixed-volume container is filled with an ideal gas at room temperature (293 K). If the gas is 500 K, what happens to the pressure and total random translational kinetic energy of the gas? Both the pressure and total kinetic energy remain constant. Both the pressure and total kinetic energy increase. Both the pressure and total kinetic energy decrease. The pressure increases while the total kinetic energy decreases. The pressure decrees while the total kinetic energy increases.

Explanation / Answer

2) The freezing point and boiling point of water is same for all linear temperature scales and hence the change in temperature is same for all the scales given here. The answer is A.

3) The reason for water freezing from top down is the anomalous behaviour of water at 4 degrees celsius. The answer is E.
