Answer:

The correct answer is A

Explanation:

In this exercise we are given a graph of temperature versus time.

In calorimeter processes there are two types

* one that when giving thermal energy to the system its temperature increases, this fundamentally due to the greater kinetic energy of the molecular ones, this process observes in the graphs as a straight line of constant slope

* A process donates all the thermal energy that is introduced is cracked in breaking the molecular bonds, taking matter from one thermodynamic state to another, for example: liquid to gas.

This process in curves as a horizontal line, that is, there is no temperature change,

When analyzing the graph shown, parts C and D are the one that show a change in temperature with thermal energy. The correct answer is A

Explain why two different elements cannot occupy the same box in the periodic table

bezimeni [28]

They cant occupy the same box in the periodic table because each atom has a certain number of protons which is the atomic number and no two atoms have the same amount of protons.

Two point charges q1 = 4. 0 µc and q2 = -8. 0 µc are placed along the x-axis at x1 = 0 m and x2 = 0. 20 m, respectively. What is

scoundrel [369]

The electric potential energy of this system of charges will be +1.44 J. Option E is correct.

<h3>What is the electric potential energy ?</h3>

Electric potential energy stands for the energy that is required to displace a charge in against an electric field.

Given data;

q₁ = 4. 0 µc

q₂ = -8. 0 µc

D(distance between charges) = 0.2 m

The electric potential energy is found as;
