Matter can change from one state to another when thermal energy is absorbed or released. A great example is Ice having its state changed to the liquid that is WATER. When ice is heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change to water, a liquid. As we all know, The change from the solid state to the liquid state is called melting.
it’s somehow re-jiggered its
taste system so that the attractant that humans used to draw the insect to
poison bait—the sugar glucose—now tastes bitter to the roach, and they avoid it.
cockroaches began appearing that avoided the baits, and did so not because they
were averse to the poison, but because they were averse to the attractant, glucose. This new
trait turned out to be heritable, that is, it had a genetic basis.
Answer:
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
Explanation
Energy can be calculated by the equation
Q = m x Cp x delta T
where
m = mass = 0.5 kg
Cp = specific heat of water = 4184 J
Delta T = 12 degrees
Multiplying all
Q = 0.5 x 4184 x 12 = 25104 Joules
Converting it to Calories
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
<h2>
<u>EARTH'S MAGNETIC FIELD</u></h2>
The magnets point North when the Earth's magnetic field has?
<h2>
<u>ANSWER</u></h2>
I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.
In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.
<h2>
<u>THE MAGNETIC REVERSAL</u></h2>
The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.
