How many calories are absorbed in a process that absorbs 0.128 joules?

Chemistry
1 answer:
earnstyle [38]3 years ago
7 0

Answer:

There are 0.0305 calories in 0.128 joules

Explanation:

Given that,

Heat absorbed, Q = 0.128 J

We need to find the heat energy absorbed in calories.

We know that the relation between joules and calories is as follows :

1 calorie = 4.184 J

1 J = (1/4.184) J

So,

0.128\ J=\dfrac{0.128 }{4.184}\\\\=0.0305\ cal

So, there are 0.0305 calories in 0.128 joules

The triple bonds are the shortest bonds. So the correct option is C.

<h3>What are bonds?</h3>

Chemical bonds are the bonds that are the attraction between ions or molecules that makes up compounds.  There are different types of bonds They are covalent, ionic, hydrogen, electrostatic, etc.

A single bond is formed when only one electron is shared between atoms. As the same triple bonds are formed when there are three electrons shared between atoms. Triple bonds are the shortest because they have less strength.

Thus, the correct option is C. triple bonds are the shortest.

Consider a gray and opaque surface at 0°c in an environment at 25°C. The surface has an emissivity of 0.8. if the radiation in
valina [46]

The radiosity of this surface is 299.95W/m².

<h3>Calculation :</h3>

Given, € 0.8

Ta=0°C 273K

For opaque body., T = 0

a+ p = 1

€ = a (Kirchoff's Law)

p = (1-E)

Radiosity = leaving energy from the surface

= px 240 +€σT4

= (1-E) × 240 +0.8 x 5.67 x 10-8 (2734)

= (1-0.8) × 240 +0.8 x 5.67 × 10-8 (2734)

= 299.95W/m²

So, now after doing the calculations we can say that the radiosity of the surface was 299.95W/m².
