Which of these would have the highest temperature?

A. ice
B. water
C. water vapor

Answers

Answer:

Water vapor

Explanation:

because water vapor is gas and gas particles move faster than solid particles (which stick together) and water particles ( with a somewhat normal movement) and the faster the particle, the hotter the substance is. With that being said C is the correct answer.

C.
Water vapour is in the gaseous states has the highest amount of Kinetic energy. Therefore, it has the highest temperature.

A student is observing a pendulum swinging back and forth. Each time it swings, the pendulum bob reaches a lower maximum, and eventually it comes to rest and hangs straight down vertically. What happens to the total energy of the pendulum? Does this violate the law of conservation of energy? Explain your reasoning.

Answers

The total energy of the pendulum stays the same. This does not violate the law of conversation of energy because that law states energy cannot be created/destroyed and the total amount of energy has stayed the same.

If the body temperature of a person is recorded as 37°C, what is the person’s body temperature in K? Round your answer to the nearest whole number.

A. 236
B. 3
C. 99
D. 310

Answers

Answer:

D

Explanation:

0 degrees Celsius is equal to 273.15 degrees Kelvin. The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15. in short : T(K) = T(°C) + 273.15

Answer: D

Explanation: 37 celsius is equal to 310.15 kelvin and if you round it to the nearest whole number you get 310.

Your science teacher has provided the following materials to investigate the factors that affect the strength of electric and magnetic forces.

• large iron nail – 5 mm diameter

• 100 cm of thinly wrapped copper wire

• D battery

• electrical tape

• wire strip

• thumb tacks -assorted sizes

• paperclips – assorted sizes

Design an investigation you could carry out to determine the factors that affect the strength of electrical and magnetic forces.

Answers

The strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.

Whta is a magnetic field?

A magnetic field can be defined as magnetic work exerted on electric charges that are in motion (movement).

Conversely, an electric field is an area where an electric current is applied and electron force can be estimated per Volts per Meter.

In conclusion, the strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.

What is a source of the pressure used to create metamorphic rocks?

The water in the ocean
The air in the atmosphere
The layers of sediment in the ocean
The magma from deep in the ground

Answers

The answer is D, or The magma from deep in the ground.

Explanation:

A wouldn’t make sense because the water in the ocean is only hot if it is the deep end of the ocean. B is incorrect because metamorphic rocks are intrusive, as far as how they form. C is incorrect because the only kind of rock classification with layers is a sedimentary rock. D is correct because as the rock sinks into the mantle, magma heats it up intensely and pressures it.
The magma from deep in the ground. Im pretty sure sorry if I’m wrong.
