Answer:

650 J are 155 calories

Explanation:

In the world, there are many differents ways to express energy. For example, for SI base units, Joule (J) is the correct way to express energy. But it is common the use of other units in differents fields. In this case, we need to convert Joules to calories. The conversion is:

4,1845 J = 1 cal

Thus:

650 J × (1 cal / 4,1845 J) = 155 cal

I hope it helps!

<u>Ans: 650 J = 155 calories</u>


<u>Given:</u>

Energy in joules = 650 J

<u>To determine:</u>

The energy in calories

<u>Explanation:</u>

1 joule = 0.2388 calories

Therefore, 650 joules = 0.2388 calories * 650 J/1 J = 155 calories

How many moles of HCl are present in 40.0 mL of a 0.035 M solution? 1. 0.0014 mol 2. 0.0060 mol 3. 0.25 mol?
Vinil7 [7]
40.0mL(1 L/1000 mL) = 0.040 L 

<span>then plug into the formula M = moles/liters </span>

<span>0.035 M = moles/ 0.040L </span>

<span>multipy both sides by 0.040L, and you get 0.0014 moles </span>

<span>so the answer is 1</span>

When the surface water temperature is still well below the water boiling temperature, some bubbles at the bottom tend to float u
irga5000 [103]

Answer:

The reasons why the seemingly floating bubbles disappear was that they tend to loss their latent heat to the water molecules at the surface water.

Explanation:

Heat energy has a considerable effect on the velocity of molecules including water. The water molecules below the container will receive much more heat energy than those above it. This heat energy in the form of specific heat capacity and latent heat that result in the increase in the speed of individual molecules of water and finally to the escape of the molecules to a colder region of the container, in this case the upper region. At the collision of the bottom water to the surface water, they tend to exchange their heat content, the hotter molecules will lose their heat to the cold ones. When the formerly hot molecules encounter this, it will result in lowering the temperature and consequentially to the reduction of their movement, once in the form of bubble, now become ordinary water. This convectional transfer of heat energy will continue until the whole system has a uniform temperature depending on the consistency of the heat source.

A bottle of 2 moles of an ideal diatomic gas experiences a temperature increase of 50.0K at constant volume. (a) Find the increa
andre [41]

Answer:

Explanation:

a) For diatomic gas: Translational motion = 3 and rotational motion = 2

∴ Total (internal energy) = 3 + 2 = 5

b) Translational + Rotational + Vibrational = 3 + 2 + 1 = 6

c) Linear molecule  

i) Non linear molecule

ii)  Monatomic molecule
