Rachel's her younger brother replace a broken part in his toy ambulance this part is responsible for converting electric energy into light energy which of these devices should they use for the replacement bulb b buzzer c motor d switch

C a motor. A wouldn't work since the bulb isn't the thing that is broken. B wouldn't work because what would the buzzer do? buzz. not convert the electrical energy. D wouldn't work unless you found something to connect the switch to. C is the only answer that makes sense to me.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
