To what temperature should soup that contains cooked beef be reheated for hot-holding?
nirvana33 [79]

The temperature , <u>165 degree F</u> should soup that contains cooked beef be reheated for hot-holding.

Food should reach a temperature serving 135°F before it can be opened in the restaurant and warmed for hot holding. Within two hours, quickly reheat the food. If food is being served right away, it can be served anywhere at temperature as long that it as it was cooked and chilled appropriately.

TCS food must be totally chilled to 41°F or even below in 6 hours after being thoroughly cooled between 135°F to 70°F in 2 hours. Within four hours, TCS food made with ingredients at room temperature needs to be chilled to 41°F or lower.

Therefore, the temperature , <u>165 degree F</u> should soup that contains cooked beef be reheated for hot-holding.

When salt is added to water, the entropy, S,
Dovator [93]

Answer:

C. number of particles

Explanation:

Entropy is the measure of disorderliness of a system. Remember that when you dissolve salt in water, you increase the number of particles in the solution. The greater the number of particles in solution, the greater the entropy of the  solution system.

Hence dissolution of a salt in water increases the entropy by increasing the number of particles in solution leading to the inequality; Ssolution > Swater + Ssalt.

A sample of a substance is found to have a mass of 223.5 grams. A graduated cylinder contains 45.6 ml of water. After a metal cy
Paraphin [41]

Answer:

We have the final answer as

<h2>9.85 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of substance = 223.5 g

volume = final volume of water - initial volume of water

volume = 68.3 - 45.6 = 22.7

volume = 22.7 mL

It's density is

density =  \frac{223.5}{22.7}  \\  = 9.84581497797...

We have the final answer as

<h3>9.85 g/mL</h3>

Hope this helps you
