Front

Which liquid had the highest molecular mass? Options: Hexane, Petroleum Ether, Ethanol, H20

Back

Hexane

Front

A scientist has that the larger the molecular mass, the larger the viscosity. Is he correct?

Back

No, because different molecular masses have differing viscosity levels.

Front

Which position produced the highest PE (potential energy)? Options: A, B, C, Both D and E

Back

A

Front

Which pigment had the highest absorption rate at 500 nm wavelength?

Back

Chlorophyll B

Front

Which pigment had the lowest absorption rate at 500 nm wavelength?

Back

Chlorophyll A

Front

Which position produced the highest KE (kinetic energy)? Options: A, B, C, Both D and E

Back

B

Front

Does the liquid with the highest density also have highest viscosity?

Back

No, because H20 has second highest viscosity while it has the highest density.

Back

Chlorophyll A

Front

Which pigment had the lowest absorption rate at 550 nm wavelength?

Back

All the same
