The specific heat of water is high; what does this mean? Group of answer choices Water has a high density. Water will always be

warmer than other materials for the same energy gain or loss. Water absorbs a higher percentage of solar energy than land does. Water must gain or lose large amounts of energy when its temperature changes.

From what we know, we can confirm that water must gain or lose large amounts of energy when its temperature changes due to its high specific heat.

<h3>What is specific heat?</h3>

This is another term used to describe heat or thermal capacity. These terms describe the amount of energy needed to change the temperature of a substance. Due to this, water requires a high amount of energy to raise its temperature by one degree.

Therefore, we can confirm that water must gain or lose large amounts of energy when its temperature changes due to its high specific heat.

2. CaCl2 (s) + 2H20 ---&gt; Ca(OH)2 (aq) + 2HCl (g) + heat<br> Is it an endothermic reaction?
antoniya [11.8K]

Answer:

no

Explanation:

Calcium chloride is a chemical compound made up of calcium ions and chlorine ions. ... Mixing calcium chloride with water is an exothermic reaction, which means that the combination of the two substances releases heat. Thus, when you add calcium chloride to water, the solution heats.

A Cessna 150 aircraft has a lift-off speed of approximately 125 km/h. What minimum constant acceleration does this require if th
aivan3 [116]

Answer:

Part a)

a = 3.65 m/s^2

Part b)

t = 9.5 s

Part c)

v_f = 55.1 m/s

Explanation:

Part a)

As we know that it starts from rest and moves on runway by total distance 165 m

so we will have

v_f^2 - v_i^2 = 2ad

v_f^2 - 0 = 2(a)(165)

v_f = 125 km/h = 34.7 m/s

now we have

a = 3.65 m/s^2

Part b)

Now for take off time we will have

v_f - v_i = at

34.7 - 0 = 3.65 t

t = 9.5 s

Part c)

v_f = v_i + at

v_f = 0 + (3.65)(15.1)

v_f = 55.1 m/s

Use F = 1/T as your basis:
DaniilM [7]
  • Frequency=60Hz

\\ \rm\rightarrowtail \nu=\dfrac{1}{T}

\\ \rm\rightarrowtail T=\dfrac{1}{\nu}

\\ \rm\rightarrowtail T=\dfrac{1}{60}

\\ \rm\rightarrowtail T=1.67\times 10^{-4}s

\\ \rm\rightarrowtail T=16.7\times 10^{-3}s

\\ \rm\rightarrowtail T=16.7ms

Okay, I have three more questions.

When a liquid or a gas is heated, it expands and becomes less dense, so it rises, while the cooler, denser liquid or gas sinks. (Not sure if this helps but this is what I hit)
