q( Joules ) = mass *specific heat of water *( temp final - temp initial)( in Celsius)
q = m Cg ∆T
q = 420 g x 4.180 J/gC (100 - 0 oC)
= 175560 Joules
in 3 significant figures
= 1.76 X 105 Joules
Freezing point.
The freezing point is the temperature at which a liquid turns into a solid, while the boiling point is the temperature at which a liquid turns into a gas. The freezing point is typically lower than the boiling point for a substance.
Boiling Point: 100 degrees celsius Freezing Point: 0 degrees celsius
The boiling point of water in Celsius is 100 degrees, and the freezing point is 0 degrees.
The boiling point of water (100°C) is higher than its freezing point (0°C) because the boiling point occurs when the vapor pressure of water equals the atmospheric pressure, which requires more thermal energy than overcoming the intermolecular forces at the freezing point.
When water is heated, it absorbs energy and its temperature rises, eventually reaching its boiling point where it turns into steam. When water is cooled, it releases energy and its temperature drops, eventually reaching its freezing point where it turns into ice.
It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance. Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
This is the property of freezing point depression and boiling point elevation. This is because of the solute absorbing the energy added to the system to heat its own molecules and so it would require more energy to boil the solvent. Likewise for freezing point depression, the molecules retain more energy.
Freezing point.
the freezing point is 0 degrees and the boiling point is 100 degrees
The freezing point is the temperature at which a liquid turns into a solid, while the boiling point is the temperature at which a liquid turns into a gas. The freezing point is typically lower than the boiling point for a substance.
Freezing point of water is 0 C and boiling point is 100 C.
The freezing point is lower and the boiling point is higher.
boiling point is 629K freezing point is 234K
According to Fahrenheit scale, freezing point of water is 32 degrees Fahrenheit (°F) and boiling point is 212 °F
0 centigrade is freezing point of water. 100 c is the boiling point of water, by defination.
