Answer: The correct answer is Option 1.

Explanation:

For the given options:

Option 1: During a phase change

Whenever phase change occurs, the temperature remains constant because the heat is used to overcome the intermolecular forces between the particles.

Option 2: During a pressure change

As we know pressure is directly related to the temperature. So, if the pressure is increased, the temperature will also increase and vice-versa.

Option 3: During a change in kinetic energy

Kinetic energy is directly related to the temperature of a substance. So, if the kinetic energy is increased, the temperature will also increase and vice-versa.

Option 4: During a change in molecular velocity

Molecular velocity is directly related to the temperature of a substance. So, if the molecular velocity is increased, the temperature will also increase and vice-versa.

Hence, the correct answer is Option 1.

What is the sign of the heat change for an exothermic reaction? for an endothermic reaction?

Julli [10]

A system that releases heat to the surroundings, an exothermic reaction, has a negative ΔH by convention, because the enthalpy of the products is lower than the enthalpy of the reactants of the system. The enthalpies of these reactions are less than zero, and are therefore exothermic reactions

A 6 kg rock is sitting at the edge of a 100 m tall cliff. What is the potential energy of the rock with respect to the ground?

Hatshy [7]

Potential energy can be calculated by the formula Pe=mgh. Plug in your values:

Pe=mgh
Pe=(6 kg)(9.8m/s^2)(100 m)
Pe=5880 kg x m^2/s^2, or 5880 Joules

If two carbon atoms are bonded by a double covalent bond, how many additional bonds can each carbon atom form?

Umnica [9.8K]

Answer:

Explanation:

Carbon Is tetravalent. This means that at any particular point in time, the number of bonds carbon can form at a particular time is 4. Now in this particular question, there is already a double bond between the two carbon atoms. This means that each of the carbon atom has the chance to fulfill it tetra valency by attaching just two bonds to itself.

Hence, to complete the property of its tetra valency, two more bonds needed to be added to the two carbon atoms
