Answer:

B. Changes in energy in systems.

Explanation:

Thermodynamics is a branch of physics which deals with heat and temperature in relation to energy work radiation and characteristics of matter.

This field studies the causes of energy changes and the effects of energy changes to chemical and physical systems.

<h2>Answer:</h2>

Thermodynamics relates B) changes in energy in systems.

<h2>Explanation:</h2>

Thermodynamics is the part of material science that manages warmth and temperature, and their connection to energy, work, radiation, and properties of issue. The conduct of these amounts is administered by the four laws of thermodynamics which pass on a quantitative depiction utilizing quantifiable naturally visible physical amounts, yet might be clarified as far as tiny constituents by factual mechanics.

Thermodynamics applies to a wide assortment of subjects in science and building, particularly physical science, concoction designing and mechanical designing, yet in addition in fields as intricate as meteorology.

MakcuM [25]

Answer:

c) No, because Celsius is not an absolute temperature scale

Explanation:

converting 5 oC to kelvin which is the absolute temperature scale gives = 273 + 5 = 278 K

and converting 20 oC to kelvin = 20 + 273 = 293 K

the ratio = 278 / 293 = 0.94 approx 1 not 4

what volume of a 0.155 M calcium hydroxide solution is required to neutralize 28.8 mL of a 0.106 M nitric acid?

Hitman42 [59]

Answer:

9.85mL

Explanation:

First, let us write a balanced equation for the reaction. This is illustrated below:

Ca(OH)2 + 2HNO3 —> Ca(NO3)2 + 2H2O

From the balanced equation above,

nA (mole of the acid) = 2

nB (mole of the base) = 1

Data obtained from the question include:

Vb (volume of the base) =?

Mb (Molarity of base) = 0.155 M

Va (volume of the acid) = 28.8 mL

Ma (Molarity of acid) = 0.106 M

Using MaVa/MbVb = nA/nB, the volume of calcium hydroxide (i.e the base) can be obtain as follow:

MaVa/MbVb = nA/nB

0.106 x 28.8 / 0.155 x Vb = 2/1

Cross multiply to express in linear form as shown below:

2 x 0.155 x Vb = 0.106 x 28.8

Divide both side by 2 x 0.155

Vb = (0.106 x 28.8) / (2 x 0.155)

Vb = 9.85mL

Therefore, the Volume of calcium hydroxide is 9.85mL
