The answer is b because Heating water makes it evaporate faster
Adding salt makes it boil at a higher temperature
Increasing the pressure would force the water from the air back into the beaker
Increasing the humidity means there are more molecules in the air, increasing the chance that our water
A: ionic salt
i've done some research and i believe it's A
Answer:
0.733 J/g °C
Explanation:
<u>Step 1 : Write formule of specific heat</u>
<u />
Q
=
mc
Δ
T
with Q = heat transfer (J)
with m = mass of the substance
with c = specific heat ⇒ depends on material and phase ( J/g °C)
Δ
T = Change in temperature
<u />
in this case :
Q = 38.5 J
<u>m = 17.5g</u>
<u>c= has to be determined</u>
<u>Δ
T = 3 (°C)</u>
<u />
<u>Step 2: Calculating specific heat</u>
⇒ via the formule Q
=
mc
Δ
T
38.5 J = 17.5g * c * 3
38.5 = 52.5 *c
c = 38.5 / 52.5
c = 0.733 J/g °C ⇒ 0.733 is reported to three significant digits due to the precision.
The specific heat of this metal is 0.733 J/g °C
Answer:
There will be 1.50 gram of water
Answer:
"A molecular, or covalent bond, is formed when atoms bond by sharing pairs of electrons. This sharing can occur from atom to atom, or from an atom to another molecular bond."
