# Absolute zero

Absolute zero is said that temperature is a physical quantity. A substance's temperature represents a measurement of its warmth or coldness. Every object or matter that exists in the universe has a temperature. Temperature can also be said to be a measure of thermal energy present inside a body. The standard unit of temperature that is used is called kelvin. Temperature and heat are two very different things. We use a device which is called a thermometer to measure the temperature of a given substance. The scales by which temperature is measured are the Celsius scale, the kelvin scale, and the Fahrenheit scale. We also call the Celsius scale the centigrade scale.

What is meant by absolute zero? Absolute zero is the lowest measure of temperature, where the heat in a body is zero. Absolute zero is also called the zero-kelvin temperature, as it measures zero on the Kelvin scale. The fundamental particles that are present in our nature show little vibration in absolute zero temperature. The absolute zero temperature has a measure of -273 degrees on the Celsius scale and a measure of 459.76 degrees on the Fahrenheit scale.

## The behavior of gases at Absolute zero

When the temperature around the particles of gas lowers, the particles move slowly. At absolute zero, the gas particles shut down and do not move, but they have some energy. Heat can never be completely removed from a substance. When the behavior of gas was being studied at different temperatures, the concept of absolute zero popped out.

Conversion of temperature from one scale to another: k = degree Celsius + 273. Degree Celsius = k – 273.

What is the kelvin value equal to 30 degrees Celsius? Putting it into the formula, k = 30 + 273 = 303 kelvin.

What is 40 degrees Celsius on the kelvin scale? Putting it into the formula, k = 40 + 273 = 313 kelvin.

What is 50 degrees Celsius on the kelvin scale? Putting it into the formula, k = 50 + 273 = 323 kelvin.

What is 60 degrees Celsius on the kelvin scale? Putting it into the formula, k = 60 + 273 = 333 kelvin.

What is 400K in the degree Celsius scale? Putting it into the formula, degree Celsius = 400-273 = 127 degrees Celsius.

What is 500K in the degree Celsius scale? Putting it into the formula, degree Celsius = 500-273 = 227 degrees Celsius.

What is 600K in the degree Celsius scale? Putting it into the formula, degree Celsius = 600-273 = 327 degrees Celsius.

What is 700K in the degree Celsius scale? Putting it into the formula, degree Celsius = 700-273 = 427 degrees Celsius.
