Thermal conductors don’t have to be hot to transfer heat. According to Ch.16, explain a situation when an ice cube would still transfer heat to another object it is in contact with.

Answers

The law of thermodynamics is that the heat transfers from a hot object to a cold one. This is how the heat gradient goes. An ice can transfer heat when it is in contact with an object which is lower in temperature. For example when ice cube touches an object of temperature -50 degree Celsius.

Answer:

Transfer of heat occurs when there is difference in the temperatures of two bodies. The temperature indicates hotness or coldness of a body. With even small difference in temperature, heat transfer occurs from hotter to the colder one till both of them achieve thermal equilibrium.

So, an ice-cube can transfer heat to another ice-cube if its temperature is higher than another. Suppose, the temperature of ice cube 1 is 0°C and another one is at -10°C, heat transfer would occur.

Scientists think that a few hundred million years or so after the Big Bang, space cooled off enough for matter to form. This matter spread out around the universe with no structure. But each little bit of matter exerted the force of _____ on each other little bit.

Answers

Answer: Gravity

Explanation: The force that is generated by matter is the gravitational force, is the force that attracts the bits of matter to each other, and is described by the equation:

F = G*(m₁*m₂)/r^2

Where G is the gravitational constant, m₁ and m₂ are the masses of the bits of matter, and r is the distance between them.

The complete paragraph is:

This matter spread out around theuniverse with no structure. But each little bit of matter exerted the force of gravity on each other little bit. Gravity is the only type of force connected with the Big Bang as it is a basic force that was to create our world in th way we can see and discover it today.

If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and the wave exhibits reinforcement, the component waves mustA. Have a different wave length than the resultant wave
B. Be in phase with each other
C. Have a different frequency than the resultant wave
D. Be traveling in the opposite direction of the resultant wave

Answers

Correct answer choice is:

B. Be in phase with each other.

____________________________________________________________

Explanation:

Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.

What environmental factors affect kinetic energy and diffusion?

Answers

There are several environmental factors that affect the kinetic energy and diffusion. The environmental factors are temperature, molecular size, and pressure, nature of the material and the concentration of the material. All the mentioned factors directly impact the kinetic energy and diffusion of a material or compound or fluid. Temperature can generally increase the kinetic energy of molecules within a compound or a substance. Increase or decrease of temperature changes the shape and nature of the material concerned. So these natural factors have a big influence on the kinetic energy and diffusion.

Answers
Temparature
Humidity (Amount of molecules in the air)

Explanation
Examples of environmental factors are, temperature, wind, pressure, humidity etc. Kinetic energy is the energy possessed by a body in motion.
This motion can be affected by factors such as rain and humidity since the make the medium more dense. It require more energy to move in a denser medium.
Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. When temperatures are high the molecules get more energy and move more faster increasing the rate of diffusion.
