## What do heating curves tell us?

Heating curves show how the temperature changes as a substance is heated up. They show how the temperature changes as a substance is cooled down.

## What is the importance of heating curve?

Heating curves are also important, in that they enable us to determine key temperatures used to identify specific substances. Melting and boiling points can be determined, based on temperatures at which plateaus exist.

## Can you heat water to more than 100 degrees?

Liquid water can be hotter than 100 °C (212 °F) and colder than 0 °C (32 °F). Heating water above its boiling point without boiling is called superheating. If water is superheated, it can exceed its boiling point without boiling.

## What is heat vs temperature?

The core difference is that heat deals with thermal energy, whereas temperature is more concerned with molecular kinetic energy. Heat is the transfer of thermal energy, whereas temperature is a property the object exhibits.

## How do heating curves work?

A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The first change of phase is melting, during which the temperature stays the same while water melts.

## How does a temperature curves affect a certain substance?

In the heating curve of water, the temperature is shown as heat is continually added. The melting and boiling points of the substance can be determined by the horizontal lines or plateaus on the curve. Other substances would of course have melting and boiling points that are different from those of water.

## What is the shape of the heating curve?

A heating curve begins from a theoretical zero and goes up in a diagonal line. As the temperature increases, it goes up. When it starts, bose-einstein condensate becomes a solid and reaches a melting point.

## Can water go above 212 degrees?

Above 212°F at standard pressure, liquid water is unstable. It will evaporate very rapidly from the surface. If the temperature is held constant (which requires some heat input, since evaporation cools things) the liquid will all evaporate. If the temperature is much above 212°F, the water will boil.

## What temp does water boil?

212°F (100°C)
Water/Boiling point
It seems like one of those basic science facts: Water boils at 212 degrees Fahrenheit (100 degrees Celsius), right? Well, not always. It depends on where you’re doing the boiling. In fact, water will boil at about 202 degrees in Denver, due to the lower air pressure at such high elevations.
