Water at 0ºF (approximately -18º C) still does have heat energy and still has molecular activity.
Thermal energy is a measure of the internal energy of a system and is not dependent on the unit of temperature used. Therefore, the thermal energy at 0 degrees Celsius would be the same as at 48 degrees Fahrenheit.
Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.
Absolute zero is -273.15 degrees Celsius and -459.7 degrees Fahrenheit. Kelvin = degrees Celsius + 273.15
It is an impossible temperature in the Celsius scale. Absolute Zero is the lowest possible temperature, the theoretical point at which no energy is present in matter. No matter can be colder than absolute zero, which is -273.15 °C or the equivalent temperature of -459.67 °F.
Absolute zero is -273.15 degrees Celsius. At this temperature, particles have minimum movement and energy.
The temperature at which molecular energy is at a minimum is known as absolute zero, which is equivalent to 0 Kelvin or -273.15 degrees Celsius. At this temperature, molecular motion ceases, and particles have the least possible energy.
Absolute 0 is negative two hundred and seventy three degrees Fahrenheit, the kelvin scale measure's this. Absolute is were no molecular movement is made. Are you positive about the -273 degrees Fahrenheit measured by the Kelvin scale? ^^ Abs. 0 = -273.15 K, or -459.67 degrees F, where molecular movement would not have enough energy to transfer electrons and thus create molecular or ionic bonds. Molecular kinetic energy is at 0.

Absolute zero is -273.15 degrees Celsius and -459.7 degrees Fahrenheit. Kelvin = degrees Celsius + 273.15
At 0 degrees Kelvin (absolute zero), molecular motion ceases and particles no longer have kinetic energy to move. At this temperature, atoms are at their lowest energy state and are not vibrating or moving.
One pound of steam at 212 degrees Fahrenheit contains 1150 BTUs of energy.
The temperature in a complete vacuum, with no heat source, would be absolute zero, which is equivalent to -273.15 degrees Celsius or 0 Kelvin. At this temperature, all molecular motion ceases, and no heat energy is present.
The form of energy caused by increased molecular activity is called thermal energy. It is a measure of the total kinetic and potential energy of the molecules in a substance due to their motion and vibration. Thermal energy determines the temperature of a substance.
Absolute zero is the coldest temperature possible - when atoms are at the lowest possible temperature level. For example, molecular movement stops (as far as quantum law allows - it seems there is a minimum energy level, where the energy is not exactly zero). This temperature is zero Kelvin, or minus 273.16 degrees on the Centigrade/Celsius scale.
