An annuity can be a single life annuity or a joint life annuity where the payments are guaranteed until the death of the second annuitant. It is regarded as ideal for retirees as it is the only income of any financial product that is fully guaranteed.
Definition: The Kelvin temperature scale is an absolute temperature scale based on the definition that the volume of a gas at constant (low) pressure is directly proportional to temperature and that 100 degrees separates the freezing and boiling points of water.
This absolute scale is known today as the Kelvin thermodynamic temperature scale. Kelvin's value of â273 was the negative reciprocal of 0.00366âthe accepted expansion coefficient of gas per degree Celsius relative to the ice point, giving a remarkable consistency to the currently accepted value.
