Water at 0ºF (approximately -18º C) still does have heat energy and still has molecular activity.

What is the temperature at which molecular energy is at a minimum?

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.


What is 0 absolut?

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.


What is absolute zero in degrees Fahrenheit?

-459.67 F


What does -270 degrees Celsius mean?

(-270) degrees Celsius = (-454) degrees Fahrenheit


Would thermal energy be greater at 0 degrees Celsius or 48 degrees Fahrenheit?

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.


Is heat energy measured in units of joules degrees Celsius and in degrees Fahrenheit?

Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.


How cold is absolute zero in Celsius?

Absolute zero is -273.15 degrees Celsius and -459.7 degrees Fahrenheit. Kelvin = degrees Celsius + 273.15


Molecular motion stop at 0 degrees?

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.


How many BTUS in 1 pound of steam at 212 degrees Fahrenheit?

One pound of steam at 212 degrees Fahrenheit contains 1150 BTUs of energy.


What is the temperature with absolutely no heat source?

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.


What is a form of energy caused by increased molecular activity and is a measure of the total energy of the substance?

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.


What temperature represents absolute zero?

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.
