What are the three ways heat is transferred

Heat is transferred by Conduction, Convection, and Radiation.

How do you spell startel

startle. The "l" comes before the "e".

Latent heat is the energy required for 1 kg of a substance to change

Latent heat is the energy required for 1 kg of a substance to change ___________. phase

What is a negative Gibbs free-energy value an indication of

Spontaneous reaction

What is the frequency of an electromagnetic wave that has a wavelength of 300000 kilometers

Frequency = (speed) / (wavelength) = (3 x 108) / (3 x 108) = 1 Hz

How does one-dimensional heat transfer differ from two-dimensional heat transfer

One dimensional heat transfer is when the temperature varition is in one direction only while two dimensional heat transfer is when temperature varies mainly in two directions (i.e x,y or r,z).

What is the electrical method to determine the specific latent heat of vaporisation

coclude the specific latent heat of vaporization

What happens to the potential energy of the molecules in a reaction

The potential energy of the molecules change during a reaction.

What instrument is used to measure electrical frequency

Frequency counter

How is stoichiometry used to calculate energy released when a mass liquid freezes

The mol is involved in many chemical calculations. And the molar mass mass is calculated from the chemical formula.

How is temperature affect the spontaneity of a reaction with positive H and S

∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.

Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom the molecule is nonpolar.
