The formula for Gibbs free energy is G = H - TS

<u>Explanation: </u>

Gibbs free energy refers a form of thermodynamic potential like Helmholtz free energy. It depends on state functions like internal potential energy, pressure, volume, temperature and entropy.

Mostly, it is the measure of reversibility or spontaneity of the chemical reaction. The change in the Gibbs free energy between the reactants and products should be less than zero or minimised to have a spontaneous or reversible chemical reaction.

The mathematical representation is,

                               G = H - TS

Here, H= U+PV, H is the enthalpy of the reaction, the measure of heat energy required to start a chemical reaction, T is the temperature and S is the entropy, the measure of randomness caused in the chemical reaction.

Describe differences between conduction and convection give examples
nevsk [136]

Explanation:

Both conduction and convection are both forms of heat transfer from one place to another.

  • In conduction, there must be contact between two bodies for the process to take place but in convection, the matter moves to transfer heat.
  • Conduction mostly occurs in solid substances whereas convection occurs mostly in fluids.
  • Heat transfer in conduction is quite slow compared to convection which is much faster.

Example of conduction is heating of iron pot when cooking

Example of convection is the refrigerating system.

3. A student measured 15.0 grams of ice in a beaker. The beaker was then
gregori [183]

Answer:

The heat that was used to melt the 15.0 grams of ice at 0°C is 4,950 Joules

Explanation:

The mass of ice in the beaker = 15.0 grams

The initial temperature of the ice = 0°C

The final temperature of the ice = 0°C

The latent heat of fusion of ice = 330 J/g

The heat required to melt a given mass of ice = The mass of the ice to be melted × The latent heat of fusion of ice

Therefore, the heat, Q, required to melt 15.0 g of ice = 15.0 g × 330 J/g = 4,950 J

The heat that was used to melt the 15.0 grams of ice = 4,950 Joules.

Assume that consumer spending increased by $4 billion while unsold business production aimed at consumers increased by $6 billio
Natali5045456 [20]

Answer:

The correct option is;

B. Increase by $4 billion

Explanation:

In Gross Domestic Product, (GDP) calculation based on the spending or expenditure approach, the spending components of the countries different economic groups are calculated

The formula for the GDP can be expressed as follows;

GDP = C + G + I + NX

Where;

C = Consumer spending or private sector consumption

G = Spending by the government

I = Economic investment

NX = Net export of goods by the economy.
