What is it about the elements in a column of the periodic table that makes them behave similarly?
electron distribution
atomic number
atomic mass
In an experiment, the variable that is deliberately changed by the scientist is called:
the manipulated variable
the controlled variable
the responding variable
The volume of a gas is doubled while the temperature is unchanged. The pressure of the gas:
is one-half the original pressure.
varies depending on the gas.
is doubled.
remains unchanged.
For a fixed mass of gas at constant temperature, Boyle’s Law states that:
the volume of a gas varies inversely with pressure.
the volume of a gas varies directly with pressure.
the temperature of a gas varies inversely with pressure.
the temperature of a gas varies directly with pressure.
At constant pressure, as the temperature of a fixed mass of gas increases, the volume will:
increase.
vary inversely.
decrease.
be unchanged.
A gas in a rigid container is heated so that its Kelvin temperature doubles. What happens to its pressure?
it doubles
nothing
it is halved
The lowest possible temperature is:
0 K
-273 K
0°C
273°C
