Describe and open, closed, and isolated system

Physics
1 answer:
PSYCHO15rus [73]3 years ago
8 0
An open system can exchange both matter and energy with the surroundings. Δ H is measured when
an open system is used as a calorimeter.

A closed system has a fixed amount of matter, but it can exchange energy with the surroundings. Δ U is
measured when a closed system is used as a calorimeter because there is no change in volume and thus no
expansion work can be done.

An isolated system has no contact with its surroundings. The universe is considered an isolated system but on
a less profound scale, your thermos for keeping liquids hot approximates an isolated system.

This lab is investigating the relationship between mass, ________, and momentum.
Sav [38]

This lab is investigating the relationship between mass, <u>Speed </u>, and momentum.

Momentum is manufactured from the mass and speed of an object. it's miles a vector quantity, owning a significance and a direction. If m is an object's mass and v is its speed, then the object's momentum is p.

Momentum in an easy way is a quantity of movement. right here amount is measurable because if an item is moving and has mass, then it has momentum. If an object no longer flows then it has no momentum. however, in regular existence, it has an important but many people didn't understand it.

Momentum gives the connection between the mass, pace, and direction of an object. Any exchange in momentum results in pressure. So, an exchange in momentum is used to determine the force appearing upon the item.

What is the number “4” in SiCl4? a subscript a coefficient a product a reactant
Svetlanka [38]

Answer: 4 is the subscript in SiCl_{4}.

Explanation:

We know that,

Subscript: The number of atom present in a given compound.

In SiCl_{4}, 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.

Coefficient: Number of atom which is used in reaction.

For example: In 3SiCl_{4}, 3 is the coefficient of silicon tetra chloride.

A Product : In the balance equation, right hand side is called product.

A reactant : In the balance equation, left hand side is called reactant.

For example: the balance equation is

2Mg+O_{2}\rightarrow 2MgO

In this equation, 2Mg+O_{2} is the reactants and 2MgO is products.

Hence, 4 is the subscript in SiCl_{4}.

Which order shows increasing energy of photons?
Alchen [17]

The correct answer is C. microwaves, infrared, visible, gamma rays

Electromagnetic waves arranged in order of  frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.

Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.

According to the Einsteins equation, E=hf, Energy is  directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.
