in order to make tea, 32,000 J of energy were added to 100.0g of water. what was the temperature Chang of the water? ​
mina [271]

Answer:

ΔT  = 76.5 °C

Explanation:

Given data:

Amount of water = 100.0 g

Energy needed = 32000 J

Change in temperature = ?

Solution,

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Now we will put the values in formula.

Q = m.c. ΔT

ΔT  = Q / m.c

ΔT  = 32000 j/ 100.0 g × 4.184 j/g. °C

ΔT  =  32000 j / 418.4 j /°C

ΔT  = 76.5 °C

GIVING THE BRAINLIEST
Allushta [10]

The correct answer is A. Charging by friction

Explanation

When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction

If the atomic number of Chlorine atom is 17 and atomic mass is 35.5u, compute the number of protons, electrons and neutrons.
lord [1]

Answer:

Protons= 17, Electrons= 17, Neutrons= 18

Explanation:

The atomic number (Z) corresponds to the number of electrons that is equal to the number of protons (17). The mass number (A) corresponds to the sum of protons and neutrons present in the nucleus (35). Therefore, we calculate the number of neutrons: 35-17 = 18

just type this into google and give me the answer 4 me plz!!!..........Describe Thomson's "plum pudding" model of the atom, and
n200080 [17]
Thomson's plum pudding model dictated that the atom contains negative charges surrounded by positive charges in close vicinity. Rutherford's experiment determined that the particles are not this close and the atom consists mainly of empty space and that it is the negative charge that surrounds the positive charge, not the other way around.
