8 0

Temperature is related to the average kinetic energy of jostling molecules. It is measured using a thermometer in degrees Celsius, Fahrenheit, or Kelvin. Thermal energy refers to the total energy of all the jostling molecules in the coffee. Your friends' smaller cups of coffee will have less thermal energy than the larger pot of coffee because these smaller cups contain a fewer number of moving molecules. How much heat is transferred from coffee to your mouth depends on difference in temperature between the coffee and your mouth. Your coffee will seem hotter if your mouth is colder from drinking ice water.

What is the approximate value of the ccc bond angle in ch3ch2ch2oh

Fynjy0 [20]

Answer:

The value of the carbon bond angles are 109.5 °

Explanation:

CH3CH2CH2OH = propanol . This is an alcohol.

All bonds here are single bonds.

Single bonds are sp³- hybdridization type. To be sp3 hybridized, it has an s orbital and three p orbitals : sp³. This refers to the mixing character of one 2s-orbital and three 2p-orbitals. This will create four hybrid orbitals with similar characteristics.

Sp3- types have angles of 109.5 ° between the carbon - atoms.

This means that the value of the carbon bond angles are 109.5 °
