## How do you calculate temperature?

It is measured on the scales of Celsius, Fahrenheit and Kelvin. The temperature change depends on the amount of heat released or absorbed. Temperature difference = amount of heat absorbed or released/ mass of the body* specific heat of the body. ΔT = Q/m*c.

## What is Fahrenheit formula?

The conversion formula for a temperature that is expressed on the Celsius (°C) scale to its Fahrenheit (°F) representation is: °F = (9/5 × °C) + 32.

## Is centigrade the same as Celsius?

Celsius, also called centigrade, scale based on 0° for the freezing point of water and 100° for the boiling point of water. Invented in 1742 by the Swedish astronomer Anders Celsius, it is sometimes called the centigrade scale because of the 100-degree interval between the defined points.

## How hot is the lava?

The temperature of lava flow is usually about 700° to 1,250° Celsius, which is 2,000° Fahrenheit. Deep inside the earth, usually at about 150 kilometers, the temperature is hot enough that some small part of the rocks begins to melt. Once that happens, the magma (molten rock) will rise toward the surface (it floats).

## Is Sun a lava?

Many people immediately think of lava, the hot, molten rock that occasionally flows from volcanoes. But even lava can’t hold a candle to the sun! At its surface (called the “photosphere”), the sun’s temperature is a whopping 10,000° F! That’s about five times hotter than the hottest lava on Earth.

## How cold is space?

If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
