1) It was Avogadro (option E).
The full name is Amadeo Avogadro. He was a famous Italian scientific. He formulated the Law that states that same volume of gases at same temperature and pressure corresponds same number of particles.
2) Cathode rays are electrons and have the largest charge mass / ratio of fundamental particles found in the atom (option E)
For example, electrons have the same charge magnitude than protons, but the mass of the electrons is a small fraction of the mass of the protons. (1/1840)
Answer is: 13500 cal.
m(water) = V(water)·d(water) = 300ml·1g/ml = 300g.
ΔT = 45°C, temperature change.
<span>Calorie is amount of </span>energy<span> (heat) needed to increase the temperature of one </span>gram<span> of </span>water by 1°<span>C.
</span><span>To raise the temperature of 300 grams of water for 45°C:
</span>Heat in calories = mass in gram x temperature change °C x specific heat (cal / gram·°C). Q = m·ΔT·c.
Q = 300g · 45°C · 1cal/g·°C = 13500 cal.
2 dots are shown for drawing it. because it has two valence electrons
Answer:
C is the answer.
Explanation:
They are both people of color who were the first to do something in their fields
Answer:
Explanation:
Synthetic fibres are made using chemicals. Hence they do not require any forest resources like wood. This helps in saving the trees from cutting down. So the production of synthetic fibers helps in the conservation of forests.
Natural fibres on the other hand require forest products like wood for its manufacture.
Hope this helps
