which best explains why greg’s hands get warm as he holds a bowl of hot soup? heat energy is created from the thermal energy in

greg’s hands. heat energy is absorbed by the soup from greg’s hands. thermal energy from the soup moves to greg’s hands. thermal energy from the surrounding air moves to greg’s hands.

Answer: the statement that <em>best explains why Greg's hands get warm as he holds a bowl of hot soup</em> is that the <em>thermal energy from the soup moves to Greg's hands</em>.


Explanation:


<em>Thermal energy</em> is the kinetic energy that the particles (atoms, molecules or ions) of a substance posses.


When hot substance (the<em> bowl of hot soup</em> that Greg holds) gets in contact with a cool substance (<em>Greg's hands</em>) part of the kinetic energy of the particles in the hotter substance is spontaneoulsy transferred to the cooler substance. This transferred energy is called heat energy.


There are three different mechanisms through which the heat energy transference is explained: conduction, convection and radiation, which are not necessary to explain here.


You just need to know that the <em>hot soup </em>transfers part of its <em>thermal energy</em> to the <em>bowl</em> walls, with which the soup is in direct contact, and the (now) hot  bowl transfers part of its thermal energy <em>to Greg's hands</em>, which now get warm.

A piece of silver releases 202.8 J of heat while cooling 65.0 °C. What is the mass of the sample? Silver has a specific heat of
KiRa [710]

Answer: 13 grams

Explanation:

The quantity of heat energy (Q) released from a heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = 202.8 Joules

Mass of silver = ?

C = 0.240 J/g °C.

Φ = 65°C

Then, Q = MCΦ

202.8J = M x 0.240 J/g °C x 65°C

202.8J = M x 15.6 J/g

M = (202.8J / 15.6 J/g)

M = 13 g

Thus, the mass of silver is 13 grams

The density of phosphorus vapor at 310 degrees celcius and 775 mmHg is 2.64g/L. what is the molecular formula of the phosphorus
lidiya [134]

Answer:

The molecular formula of the phosphorus is P4

Explanation:

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

Density of phosphorus vapor at 310 °C and 775 mmHg = 2.64g /L

<u>Step 2: </u>Calculate the molecular weight

We assume phosphorus to be an ideal gas

So p*V = n*R*T

 ⇒ with p = the pressure of phosphorus = 775 mmHg

⇒ with V = the Volume

⇒ with n = the number of moles = mass/molecular weight

⇒ with R = ideal gas constant  = 0.08206 L*atm/K*mol

⇒ with T = the absolute temperature

p*V = m/MW *R*T

MW = mRT/PV

 ⇒ Since the volume is unknown but can be written as density = mass/volume

MW = dRT/P

MW = (2.64g/L * 0.08206 L*atm/K*mol * 583 Kelvin)/1.0197 atm

MW = 123.86 g/mol

<u>Step 3</u>: Calculate molecular formula of phosphorus

The relative atomic mass of phosphorus = 30.97 u

123.86 / 30.97 = 4

The molecular formula of the phosphorus is P4

Explain why you cannot just take away a proton to make a halogen negative.​
Ilia_Sergeevich [38]

The force that holds protons and neutrons together is too strong to overcome.

<h3>Explanation</h3>

Consider the location of the particles in an atom.

  • Electrons are found outside the nucleus.
  • Protons and neutrons are found within the nucleus.

Protons carry positive charges and repel each other. The nucleus will break apart without the strong force that holds the protons and neutrons together. This force is much stronger than the attraction between the nucleus and the electrons. X-rays are energetic enough for removing electrons from an atom. However, you'll need a collider to remove protons from a stable nucleus. You could well have ionized the atom with all that energy.

Also, changing the number of protons per nucleus will convert the halogen atom to an atom of a different element. Rather than making the halogen negative, removing a proton will convert the halogen atom to the negative ion of a different element.
