Gay- Lussacs law states that the pressure of a gas is directly proportional to temperature for a fixed amount of gas at constant volume.
therefore P/T = k
where P - pressure , T - temperature and k - constant
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in kelvin - 110 °C + 273 = 383 K
T2 - 65.0 °C + 273 = 338 K
substituting these values in the equation
P = 19.9 psi
new pressure is 19.9 psi
Answer:
a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body.
Explanation:
Answer:
There was an electron transfer where the marble has lost the same amount of electrons (being positively charged) that the piece of silk has gained (being negatively charged).
Explanation:
As a result of this transfer of electrons and the charges induced in the objects they will attract.
When a body is endowed with electrical properties, that is, it acquires electrical charges, it is said to have been electrified.
Electrification is one of the phenomena that studies electrostatics.
To explain how static electricity originates, we must consider that matter is made of atoms, and atoms of charged particles, a nucleus surrounded by a cloud of electrons. Normally, matter is neutral (not electrified), it has the same number of positive and negative charges.
Some atoms are easier to lose their electrons than others. If a material tends to lose some of its electrons when it comes into contact with another, it is said to be more positive in the Triboelectric series. If a material tends to capture electrons when it comes into contact with another material, that material is more negative in the triboelectric series.
Answer:
pOH = 13.246
Explanation:
pH = -log[H+]
[H+] = [HBr] porque HBr es un acido fuerte.
pH = -log(0.176) = 0.754
pH + pOH = 14
pOH = 14 - 0.754 = 13.246
