Solid iron prllets are heated, melted and drawn into wires. This is an example of a chemical reaction. True or False​
monitta

Answer:

False

Explanation:

It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.

Most physical changes are often phase changes.

  • A phase change is a change in the physical state of a body.
  • In this change, it is from solid to liquid.
  • Now new substances are formed.
  • When substances are changed from one form to another, it is a physical change.

In a chemical change, a new substance is formed at the end of the process.

Why must energy be controlled?​
eduard

Answer:

Energy should be saved and controlled as it is better for the environment. Excess use of energy of any kind can be disastrous. For example, a kind of energy is stored in the food. If excess food is consumed and wasted, then the country and other people will have to face consequences of it. Malnutrition will rise.

Another kind of energy is the energy in the fuel. If fuel consumption is not controlled then in the near future the resources for the making of fuel will be depleted.

A helium balloon with an internal pressure of 1.00 atm and a volume of 4.50 L at 20.0 °C is released. What volume will the ballo
meriva

Answer:

The balloon will occupy a volume of 6.48 L

Explanation:

<u>Step 1: </u>Data given

internal pressure = 1.00 atm

volume = 4.50 L

Temperature = 20.0 °C

<u>Step 2:</u> Calculate new volume via the ideal gas law

P*V = n*R*T

(P1*V1)/ T1 = (P2*V2)/T2

⇒ with P1 = 1.00 atm

⇒ with V1 = 4.50 L

⇒ with T1 = 20.0 °C = 293 Kelvin

⇒ with P2 = 0.600 atm

⇒ with V2 = TO BE DETERMINED

⇒ with T2 = -20°C = 253 Kelvin

(1.00atm * 4.50 L)/293 Kelvin = (0.600 atm*V2) / 253 Kelvin

0.01536 = 0.00237 V2

V2 = 6.48 L

The balloon will occupy a volume of 6.48 L

Using Charles law if the volume of a gas is 5.0 L when the temperature is 5.0C what will the new volume be if the temperature is
Vikentia [17]

Answer:

The answer to your question is   V2 = 5.09 l

Explanation:

Data

Volume 1 = V1 = 5.0 L

Temperature 1 = T1 = 5°C

Volume 2 = V2 = ?

Temperature 2 = T2 = 10°C

Formula (Charles law)

             V1/T1 = V2/T2

-Solve for V2

                  V2 = V1T2 / T1

-Convert temperature to °K

T1 = 5 + 273 = 278°K

T2 = 10 + 273 = 283°K

-Substitution

                 V2 = (5)(283) / (278)

-Simplification

                 V2 = 1415 / 278

-Result

                 V2 = 5.09 l
