A substance registers a temperature change from 20 to 40 to what incremental temperature change does this correspond

Chemistry
1 answer:
ss7ja [257]3 years ago
3 0

<u>Given:</u>

Initial temperature, T1 = 20 C

Final temperature, T2 = 40 C

<u>To determine:</u>

The temperature change

<u>Explanation:</u>

Convert degree C to Kelvin

Temperature in Kelvin = degree C + 273

T1 = 20 + 273 = 293 K

T2 = 40 + 273 = 313 K

Incremental temperature change = T2 - T1 = 313-293 = 20 K

Ans: The temperature change in kelvin is 20 K

In the deep space between galaxies, the density of atoms is as low as 106 atoms/m3, and the temperature is a frigid 3.0 K. What
Savatey [412]

Answer:

4.388*10^-^2^1

Explanation:

Given:

N/V= 106 atoms/m^3

T=3.0K

we know the values of

K_{b} =1.38*10^-^2^3 J/K

N_{A} =6.02*10^2^3/mol

Formula:

PV=NK_{b} T

rearranging the formula and substituting values

P=(NK_{b} T)/V

P=(106)(1.38*10^-^2^3)(3)

P=4.388 *10^-^2^1 Pa

Which of the following objects would require the use of a large-scale model A. An atom B. A car engine C. A frog's heart D. The
levacccp [35]

Answer:

A. An atom

Explanation:

A large scale model is one that is bigger than the object itself. These are needed to visualise structures and behaviours that we cannot normally see. A large scale model is needed for small objects, such as an atom. Larger objects do not need<em> even bigger</em> models

3NO2− + 8H+ + Cr2O72− → 3NO3− +2Cr3+ + 4H2O
Reptile [31]
According to this reaction:
3NO2^-  +  8 H^+  +  Cr2O7^-2 → 3NO3^- +  2Cr^+3 + 4 H2O
(1) 3 NO2^-  → 3NO3^-, The oxidation state of nitrogen converted from +3 to +5 
i.e oxidation process, ∴ NO2^-  is reducing agent.
(2) Cr2O7^-2 → 2Cr^+3, The oxidation state of Cr converted from +6 to +3
i.e reduction process ∴ Cr2O7^-2 is an Oxidizing agent. 
(3) H^+ → H2O, the oxidation state of Hydrogen is still +1, i.e No change (neither)
