how much energy is transferred when 1 gm of boiling water at 100 degree celcius condenses to water at 100 degree celcius?

Answers

Answer 1

Answer: The latent heat of vaporization for water is 2257 KJ per Kg . I'm pretty sure that's exactly the same as 2257 joules per gram. So ... When 1 gm of STEAM at 100 C condenses to 1 gm of liquid water at 100 C, it releases 2257 joules of heat energy to its environment.

Answer 2

Answer: 22.5 x 10 to the power 5 kilo/joules energy is transferred when boiling water at 100 degree celcius condenses to water at 100 degree celcius

A ball of a mass 0.3 kg is released from rest at a height of 8 m. How fast is it going when it hits the ground? Acceleration due to gravity is g=9.8 m/s^2

Answers

In order to solve this problem, there are two equations that you need to know to solve this problem and pretty much all of kinematics. The first is that d=0.5at^2 (d=vertical distance, a=acceleration due to gravity and t=time). The second is vf-vi=at (vf=final velocity, vi=initial velocity, a=acceleration due to gravity, t=time). So to find the time that the ball traveled, isolate the t-variable from the d=0.5at^2. Isolate the t and the equation now becomes $√((2d)/a)$ . Solving the equation where d=8 and a=9.8 makes the time $√((2*8)/9.8)$ =1.355 seconds. With the second equation, the vi=0 m/s, the vf is unknown, a=9.8 m/s^2 and t=1.355 sec. Substitute all these values into the equation vf-vi=at, this makes it vf-0=9.8(1.355). This means that the vf=13.28 m/s.

Answer:

The answer is 12.5 m/s

v=the square root of 2 x(gh)

or v = the square root of 2 x (9.8 x 8)

What type of interference results in beats?constructive
destructive
negligible
interference is not involved in the creation of beats

Answers

Answer: constructive

Explanation:

Two waves having slightly different frequencies when interfere constructively produce beats. Superposition of these two waves results in addition of amplitudes of the two waves. The amplitude of the resultant wave vibrates or beats.

Beat frequency is given by the absolute difference between the frequencies of the two waves.

b = |f₂ - f₁| = f₂ - f₁ or f₂ + f₁

The answer is A Constructive.

Explain why dissolving is a physical change

Answers

It's a physical change because it is changing from one matter to another.

because the kinetic energy start to decrease, for example if we put sugar in a high temperature tea and we shake it what will happen to the sugar will the kinetic energy increase or decrease, it will probably decrease, just like us the people when we enter a cold room and we have a hot temp.

A ball is thrown into the air with an initial upward velocity of 60 ft/s. Its height (h) in feet after t seconds is given by the function h = –16t² + 60t + 6. What will the height be at t = 3 seconds?A.) 35 feet
B.) 40 feet
C.) 42 feet
D.) 45 feet

Answers

To answer the question, directly substitute the value given for t to the given function of height.
h = -16t² + 60t + 6
h = (-16)(3 s)² + (60)(3) + 6 = 42
Therefore, the height of the ball after 3 seconds is 42 ft.

Answer:

The height of the ball when it hits t = 3 seconds will be 42 feet.

Explanation:

The user above me provides a very helpful explanation, so I am only writing this in his/her/their honor for his/her/their work :D

h = -16t² + 60t + 6

h = (-16)(3 s)² + (60)(3) + 6 = 42

Deep currents flow along the __________.halocline
ocean floor
ocean surface
thermocline

Answers

Your answer would be that deep currents flow along the ocean floor.

Final answer:

Deep ocean currents primarily flow along the ocean floor, driven by variations in water density. The halocline and thermocline are transitional layers in the ocean, but do not direct deep current flow.

Explanation:

Deep currents in the ocean predominantly flow along the ocean floor. These are also known as deep-ocean or abyssal currents. Unlike surface currents, which are mainly driven by wind, deep ocean currents are driven by variations in water density, which involves factors such as differences in temperature and salinity. The halocline and thermocline refer to transitional layers within the ocean where salinity and temperature change rapidly, respectively. However, they do not necessarily direct the flow of deep currents.
