Object A at 40.°C and object B at 80.°C are placed in contact with each other. Which statement describes the heat flow between t
alukav5142 [94]

Answer: The correct option is 2.

Explanation: Heat flow is defined as the transfer of energy from hotter object to cooler object when two objects are kept together at different temperatures. As the energy remains conserved, so the heat flow will take place until the equilibrium is attained.

In the above asked question, Object A is at 40° C and Object B is at 80° C.

Object B is at higher temperature, so the heat flow will take place from Object B to Object A.

Hence, the correct option is 2.

Reika [66]

The molecular formula is the sum of the atomic masses of all atoms in the molecule.

The formula of Soda Ash:

Na₂CO₃ is also known as Sodium Carbonate.

The molecular mass of Soda Ash is

(2×Na)+(1×C)+(3×O)=106g/mol

The formula of Baking Soda:

NaHCO₃ is also known as Sodium bicarbonate.

The molecular mass of Baking Soda is

(1×Na)+(1×H)+(1×C)+(3×O)=84g/mol

The formula of Lime Stone:

CaCO₃ is also known as Calcium carbonate.

The molecular mass of Lime Stone:

(1×Ca)+(1×H)+(1×C)+(3×O)=100g/mol

The formula of Ethanol:

C₂H₅OH is the formula of ethanol.

The molecular mass of Ethanol:

(2×C)+(6×H)+(1×O)=46g/mol

The formula of Common Salt:

NaCl is also known as Sodium chloride.

The molecular mass of Common Salt:
