There are different ways for transfer of heat. investigation designs explains the heat transfer when atoms directly touch is Hands touching the handle of pan sitting on a lit Bunsen burner.

In conduction, When two objects touch, heat from the hotter object is said to be transferred to the cooler object.

Heat as a flow of energy often arise from a higher temperature object to a lower temperature object.

The temperature that exist difference between the two neighboring objects can lead heat transfer.

The heat transfer is still ongoing until the two objects have attained thermal equilibrium and are found in the same temperature.

in the excretory system, where does the waste material in the body come from and why does the body need to get rid of these wast
julsineya [31]

In the excretory system, the waste materials are filtered from the blood. They are gotten rid off in order to maintain internal chemical homeostasis.

<h3>What is the Excretory System?</h3>

The excretory system can be described as a biological system that aids the body in removing unwanted materials from fluids of the body of organisms.

The main reason for the function of the excretory system is to maintain internal chemical homeostasis and prevent the body from damage.

How many electrons pass through a 20-ohms resistor in 10 min if there is a potential drop of 30 volts across it?
tangare [24]

The number of electrons passes through 20 ohms resistor in 10  minutes is 5.625e+21.

<h3>What is a resistor?</h3>

In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.

Given, the resistance is 20 ohms.

The potential difference is 30 volts

Time is 10 minute

By the formula of current

\rm I = \dfrac{30}{20} = 1.5 \;C/s

The charge flowing through the resistor is 1.5 C/s

1 electron charge is 1.6e+19

Now, the number of electrons passing through a 20 ohms resistor is

\dfrac{1.5}{1.6e+ ^2^1} = 0.9375e+^1^9

In 10 minutes

0.9375e+^1^9 \times 60 \times 10 = 5.625e+^2^1

Thus, the number of electrons passes through 20 ohms resistor in 10  minutes is 5.625e+21.

Krypton is named after the Greek word that means “secret.” Which explains why krypton was most likely given this name?
bekas [8.4K]

Answer:

Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret.

Explanation:

Krypton (₃₆Kr), an element with atomic number 36, belongs to group 18 on the periodic table of elements. This group is a specific one - it's made up of elements known as noble gases. Besides krypton, these elements are: helium, neon, argon, xenon, and radon. All noble gases were characterized relatively late compared to other elements. They all conduct electricity, fluoresce, and are odorless and colorless. Besides that, they have very low chemical reactivity. Because of their stability, they are often used to maintain a safe, constant environment. As krypton shares all of these characteristics, it was difficult for chemists to find it. That's why it was most likely given that name.
