You open the refrigerator and take out a slice of leftover pizza. You put it in the microwave oven, turn it on, and watch for th

e cheese to start bubbling. You take a bite of the pizza and realize it is too hot, so you let it sit on the counter for a minute. When the pizza is finally cool enough to eat, you enjoy your lunch. Identify three examples of energy transfer in the scenario.
Pick up to 3 answers.
A. Electromagnetic (microwave) energy is transferred from the refrigerator to the pizza in the refrigerator.
B. Electromagnetic (microwave) energy is transferred from the microwave to the pizza in the microwave oven.
C. Heat energy is transferred from the pizza to the room as the pizza cools on the counter.
D. Heat energy from the warm pizza is transferred from the pizza into the mouth chewing it.
E. Heat energy from the room is transferred into the pizza as it comes out of the microwave oven.

An alloy of bronze is manufactured by melting 51.2 g of copper with 6.84 g of tin. What is the percent copper in the bronze?
Harlamova29_29 [7]

Answer:

Percentage of copper = 88%

Explanation:

Given data:

Mass of copper = 51.2 g

Mass of tin = 6.84 g

Percentage of copper = ?

Solution:

Formula:

Percentage of copper = mass of copper / total mass × 100

Now we will determine the total mass:

Total mass = mass of copper + mass of  tin

Total mass = 51.2 g + 6.84 g

Total mass = 58.04 g

Now we will calculate the percentage of copper.

Percentage of copper = 51.2 g / 58.04 g × 100

Percentage of copper = 0.88 × 100

Percentage of copper = 88%

Find the fugacity coefficient of a gaseous species of mole fraction 0.4 and fugacity 25 psia in a mixture at a total pressure of
Oksana_A [137]

<u>Answer:</u> The fugacity coefficient of a gaseous species is 1.25

<u>Explanation:</u>

Fugacity coefficient is defined as the ratio of fugacity and the partial pressure of the gas. It is expressed as \bar{\phi}

Mathematically,

\bar{\phi}_i=\frac{\bar{f_i}}{p_i}

Partial pressure of the gas is expressed as:

p_i=\chi_iP

Putting this expression is above equation, we get:

\bar{\phi}_i=\frac{\bar{f_i}}{\chi_iP}

where,

\bar{\phi}_i = fugacity coefficient of the gas

\bar{f_i} = fugacity of the gas = 25 psia

\chi_i = mole fraction of the gas = 0.4

P = total pressure = 50 psia

Putting values in above equation, we get:

\bar{\phi}_i=\frac{25}{0.4\times 50}\\\\\bar{\phi}_i=1.25

Hence, the fugacity coefficient of a gaseous species is 1.25
