Hi there!
Gallium is chemical element 31, (meaning 31 protons, 31 electrons).
The symbol for Gallium is "Ga"
Hope this helps you!

I believe the answer is A, temperature and number of particles are constant. Correct me if i'm wrong :)
Answer:
750W
Explanation:
40×10= 400N
work done= force × distance
=400 × 75
=30000 J
Power= work done/ time
= 30000 ÷ 40
= 750 W
From the information given and if the question is complete then;
Absolute temperature is the temperature in Kelvin
To convert degree Celsius to kelvin we normally add 273
that is Kelvin = deg Celsius + 273
Thus since we have been given that the air was at -70 degrees celcius;
then; - 70° C + 273 = 203 K
Therefore; the absolute temperature is 203 K
The answer is: "isotopes" .
