Hans Selye’s general adaptation syndrome theory proposes that adaptation to stress occurs in how many stages?
ANTONII [103]

<u>Answer:</u>

Adaption to stress occurs in three stages: alarm, fight or flight, exhaustion.

<u>Explanation:</u>

According to the general adaptation syndrome theory proposed by Hans Selye, the adaption to stress occurs in three stages which are:

1. alarm

2. fight or flight

3. exhaustion

This is a process which comprises of three stages that describes the physiological changes which a body undergoes when in stress (an emotional, mental and physical human response to a specific stimulus).

A student attempted to measure the specific latent heat of vaporisation of water.
tensa zangetsu [6.8K]

Answer:

The latent heat of vaporization of water is 2.4 kJ/g

Explanation:

The given readings are;

The first (mass) balance reading (of the water) in grams, m₁ = 581 g

The second (mass) balance reading (of the water) in grams, m₂ = 526 g

The first joulemeter reading in kilojoules (kJ), Q₁ = 195 kJ

The second joulemeter reading in kilojoules (kJ), Q₂ = 327 kJ

The latent heat of vaporization = The heat required to evaporate a given mass water at constant temperature

Based on the measurements, we have;

The latent heat of vaporization = ΔQ/Δm

∴ The latent heat of vaporization of water = (327 kJ - 195 kJ)/(581 g - 526 g) = 2.4 kJ/g

The latent heat of vaporization of water = 2.4 kJ/g

What is the amount of electric current passing through the heating oil of a hot plate if 25 C of charge passes through it in 7 s
coldgirl [10]

Answer:

Current, I = 3.57A

Explanation:

A current of I amperes means that I Coulombs of charge flows through the conductor (heating coil) per second.

Therefore, in time t, the total charge (Q) passing through any point in which the current (C) flows will be given by the equation;

Q = It

Where; Q is the charge in coulombs; I is the current in amperes; t is the time in seconds.

From the question, we were given the following parameters;

Q = 25C, t= 7secs and I =?

From the equation, Q = It

We make current, I the subject of formula;

Thus, I = Q/t

Substituting into the equation;

I = 25/7

I = 3.57Amp.
