the phase change of boiling has more kinetic energy.

boiling is a liquid ---> gas

melting is solid ---> liquid

in a liquid, there is medium kinetic energy but when a liquid is boiled it turns into a gas and gains more kinetic energy, so there is more movement and the particles move freely as there is high KE.

in a solid, there is low kinetic energy as the particles vibrate in fixed positions. a solid gains kinetic energy when it becomes a liquid (melting) and there is medium kinetic energy.

there is a higher amount of kinetic energy when a substance is boiled.

therefore, the answer is boiling.

The instruction booklet for your pressure cooker indicates that its highest setting is 11.8 psipsi . You know that standard atmo

Answer: The temperature at which the food will cook is 219.14°C

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=14.7psi\\T_1=273K\\P_2=(14.7+11.8)psi=26.5psi\\T_2=?$

Putting values in above equation, we get:

$\frac{14.7psi}{273K}=\frac{26.5psi}{T_2}\\\\T_2=\frac{26.5\times 273}{14.7}=492.14K$

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

$T(K)=T(^oC)+273$

$492.14=T(^oC)+273\\\\T(^oC)=219.14^oC$

Hence, the temperature at which the food will cook is 219.14°C

Elements can't be broken down, into a simplre set of properties. They are one strict unit & cannot be broken down, however they can be added together to make a compound.

HOPE THIS HELPS & good luck <3 !!!!!
