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.
Temperature Scales. Temperature is the level of heat in a gas, liquid, or solid. Three scales are commonly used for measuring temperature. The Celsius and Fahrenheit scales are the most common. The Kelvin scale is primarily used in scientific experiments.onverting Temperatures. It is sometimes necessary to convert temperature from one scale to another. Here is how to do this. 1  To convert from ÂºC to ÂºF, use the formula: ÂºF = ÂºC x 1.8 + 32.
