# Understanding the Constant Temperature of Phase Transitions

• Tulatalu
In summary, temperature is a measure of the average kinetic energy of particles in a substance, while heat is the transfer of thermal energy between objects. Temperature is typically measured using a thermometer and can be expressed in units such as Celsius, Fahrenheit, and Kelvin. Factors such as energy from the sun, material composition, and physical properties can affect the temperature of a substance. Living organisms are highly impacted by temperature, as it plays a critical role in their survival and function. Organisms have adapted to specific temperature ranges and use various mechanisms to regulate their internal temperature.

Why does the temperature of boiling or melting water remain constant?

You mean during the phase transition? Because all additional energy furnished to the system goes to producing the phase transition. A substance requires energy to go from solid to liquid or from liquid to gas. Look up latent heat.

## 1. What is the difference between temperature and heat?

Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of thermal energy from one object to another.

## 2. How is temperature measured?

Temperature is typically measured using a thermometer, which contains a liquid (such as mercury) that expands or contracts based on the temperature and is then read on a scale.

## 3. What are the units of temperature?

The most common units of temperature are Celsius (°C) and Fahrenheit (°F). However, Kelvin (K) is also widely used in scientific research and is based on the absolute zero point of -273.15°C.

## 4. What factors affect temperature?

The temperature of a substance can be affected by several factors, including the amount of energy it receives from the sun or other sources, the type of material it is made of, and its physical properties such as color and texture.

## 5. How does temperature impact living organisms?

Temperature plays a crucial role in the survival and function of living organisms. Too high or too low temperatures can be harmful or even fatal. Organisms have adapted to specific temperature ranges and use various mechanisms to regulate their internal temperature.
