Based on what you've learned about heat energy, explain the factors that would determine how quickly a piece of meat cooked on a

barbecue grill. Why would the amount of water in the meat affect the speed of cooking?

Answer and Explanation:

Heat is a form of energy. It is the total energy of a system associated to the the movement of its molecules or molecular motion.

It depends on various factors like enthalpy of the system, its pressure, temperature, etc.

In the case mentioned, the pace at which meat is cooked on a barbecue grill depends on the water content of the meat and the barbecue grill temperature.

The reason for the cooking speed being affected by amount of water in the is that meat heat energy required to remove the excess water for the proper cooking depends on the water content which if removed completely will result in uncooked meat.

The more the water content the more is the energy requirement to remove it.

Answer:

Explanation:

Water has a very high specific heat capacity of about 4.186 J/C. This means that the more water that a piece of meat holds, the longer is takes to cook since the water requires more energy to remove from the meat.

The speed of cooking also depends on factors such as the thickness of the meat and the temperature of the grill. The thicker a piece of meat is, the longer it takes for the entire piece of meat to heat completely through. The higher the temperature of the grill, the quicker the heat energy spread throughout the meat.

A light ray strikes a plane mirror at an angle of 23° to the normal. What is the angle between the reflected ray and the mirror?
tiny-mole [99]

Answer:67^{\circ}

Explanation:

Given

Ray of light incident on plane making an angle of 23^{\circ} with normal

Thus incident angle i=23^{\circ}

So according to the law of incidence is equal to angle of reflection

\angle i=\angle r

thus \angle r=23^{\circ}

and angle between mirror and reflected ray =90^{\circ}-23^{\circ}

=67^{\circ}

A student stays at her initial position for a bit of time, then walks slowly in a straight line for a while, then stops to rest
IRINA_888 [86]

Answer:Average speed is greater than average velocity.

Explanation  :

Given

student walks slowly along a straight line for a while ,then stops to rest a while, and finally runs quickly back to her initial position

Let x be the length of track and the whole process takes t time

For average speed =\frac{distance\ traveled}{time\ taken}

Average speed=\frac{2x}{t}

For average velocity =\frac{Displacement}{time\ taken}

Since displacement is zero as she returns to its initial position.

Average velocity=0

Therefore Average speed is greater than average velocity.

Study the diagram and calculate the effort required to balance the load​
Lisa [10]

Answer:

Solution given;

load =600N

effort=?

load distance: 0.6m

effort distance;2.6m

we have

load *load distance :effort *effort distance

0.6*600=effort *2.6

360/2.6=effort

effort:138.46N

A backpacker collects snow at 0°C, and places it in a cooking pot on a camp stove. It takes 643 kJ of heat energy to melt the sn
Nitella [24]

Answer:

The mass of snow that the backpacker collected is: <em>D) 855g</em>

Explanation:

To boiling the water, the cooking pot requires 643kJ. This heat is due to the heat to melt the water and the heat to bring the water to boiling point.

The heat to melt the water is:

q = ΔHfusion×\frac{1mol}{18,02g}×mass

And heat to bring water to boiling point is:

q = C×mass×ΔT

Where C is specific capacity of liquid water and ΔT is change in temperature (100°C, from melting point to boling point)

As the required energy required is 643000J:

643000J =  ΔHfusion×\frac{1mol}{18,02g}×mass + C×mass×ΔT

643000J =  6020J/mol×\frac{1mol}{18,02g}×mass + 4,18J/g°C×mass×100°C

643000J = 334J/g×mass + 418J/g×mass

643000J = 752J/g×mass

855g = mass

<em>The mass of snow that the backpacker collected is 855g</em>

I hope it helps!
