Which of the following does not represent the freezing point of water?

50% Answer Correctly

	0°F
	273K
	0°C
	32°F

Solution

The Fahrenheit scale fixes the freezing point of water at 32°F, the Celsuis scale at 0°C, and the Kelvin scale at 273K.

Blood pressure is generally highest in which of the following?

61% Answer Correctly

	heart
	capillaries
	arteries
	veins

Solution

Which of the following is not true about simple magnets?

62% Answer Correctly

	same poles repel each other
	opposite poles repel each other
	all of these are untrue
	opposite poles attract each other

Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.

The transfer of heat by the circulation or movement of the heated parts of a liquid or gas is called:

61% Answer Correctly

	convection
	radiation
	conduction
	diffusion

Solution

Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Examples of heat transfer by convection include water coming to a boil on a stove, ice melting, and steam from a cup of coffee.
