This is thermal conduction.
In conduction area with higher kinetic energy (in this case how water) transfer thermal energy to an area with lower kinetic energy (in this case frozen vegetables). Thermal c<span>onduction takes place in all phases of </span>matter (solids, liquids, gases). Rate of conduction is proportional with <span>temperature difference between substances.</span>

Can someone please help me with this it's for a grade.
alukav5142 [94]

Answer:

The Answer is 'D'

Explanation:

The diagram on the down side shows the behavior of the particles of a liquid so I suppose it is the ocean. While the top diagram shows the behavior of the particles of a gas so I am sure it's the air. Therefore I chose the last diagram because it describes exactly how you wanted in the question, which is the Ocean's water evaporating to become gas or the 'air' as we say

A 75.0-milliliter lightbulb is filled with neon. There are 7.16 × 10-4 moles of gas in it, and the absolute pressure is 116.8 ki
Fantom [35]

Answer:- 1467 K

Solution:- It asks to calculate the kelvin temperature of the light bulb. Looking at the given info, it is based on ideal gas law equation, PV=nRT.

Given: n=7.16*10^-^4moles

V = 75.0 mL = 0.0750 L

P = 116.8 kPa

We know that, 101.325 kPa = 1 atm

So, 116.8kPa(\frac{1aym}{101.325kPa})

= 1.15 atm

R is universal gas constant and it's value is 0.0821\frac{atm.L}{mol.K} .

T = ?

Let's plug in the values in the equation and solve it for T.

1.15(0.0750)=7.16*10^-^4*0.0821(T)

0.08625 = 0.00005878(T)

T=\frac{0.08625}{0.00005878}

T = 1467 K

So, the temperature of the light bulb would be 1467 K.

Five drops of 1.0M NaOH increase the pH of a solution from 3.0 to 4.6. Five additional drops of 1.0M NaOH increase the pH to 4.7
Andrej [43]
The solution is buffered with a weak acid and it's conjugate base. Since NaOH is a base, you can use a weak acid as it's buffer.

I don’t get this pls help
igor_vitrenko [27]

Answer:

light

According to Newtonian gravity, light is not affected by gravity, as light is massless. Einstein's law E = mc 2, immediately suggests that light is affected by gravity. This is indeed the case and has experimentally be observed via gravitational lensing and other effects.

Explanation:

I thought I'd just answer here as well so I can get a couple extra points :)

I'm super glad I helped <3
