The answer is B.

A. Particles are always vibrating. The hotter the object, the more average kinetic energy the particles have, and thus vibrating faster. If the matter is cooled down to absolute zero (ie. 0K or -273°C), the particles will stop vibrating as they lose all the kinetic energy.

B. Particles in solids are vibrating within a fixed location. They are closely packed together, forming a regular and fixed shape. When the solids are heated up and become liquid or gas, the particles will gain potential energy, which allows them to move around and further apart from each other. Thus, liquid and gas do not have a fixed shape.

C. Intermolecular forces are the chemical bonds (eg. ionic bond, covalent bond) among atoms and molecules. Stronger bonds result in a higher boiling point and melting point as more energy is required to break the forces. Yet, even substances with weak intermolecular forces could still be frozen to solid, so the strength of the bonds does not affect the physical states of the substance.

D. For the same kind of substance, solid has a lower temperature than liquid and gas. Temperature is proportional to the average kinetic energy of the particles, so the particles vibrate less vigorously. Yet, taking water and ice as an example, if you have a large piece of ice and a drop of water, although the average kinetic energy of ice is lower than that of water, the total kinetic energy of the particles in the ice could still be larger than that in the water, since there are many more particles in the ice.

Furkat [3]

Answer:

True

Explanation:

Insight therapies are very powerful psychological tools used by therapist to help them unlock their past and provide a better well being and a more sound future.

  • It involves verbal communication between the client and the therapist.
  • The stages are grouped into sessions where both parties frequently meet.
  • Issues in the past that might be the premise of current behaviors are focused on.
  • The goal is to be able to annul the effect such issues currently have on the present lifestyle of the client.

A current of 15.0 A flows through an electric heater operating on 120 V. Compute the power consumption of the electric heater.
Rzqust [24]

Answer:

There will be 1800 W power consumption in heater

Explanation:

We have given current flowing in the heater I = 15 A

Voltage on which heater is operating V = 120 volt

We have to find the power consumption in the heater

We know that power consumption is given by P = VI

So power consumption in heater = 120 × 15 = 1800 W

So there will be 1800 W power consumption in heater
