If you are talking about Isotopes then I believe it is the amount of atoms that have different amounts of neutrons ,but the same number of protons.
Answer:Calculate the thermal energy change when 0.200 kg of water cools from 100°C to 25.0°C.
change in temperature = (100 - 25) = 75.0°C.
change in thermal energy = mass × specific heat capacity × change in temperature.
= 0.200 × 4,180 × 75.0.
= 62,700 J (62.7kJ)
Explanation:
So the equation ask to calculate on how much can you lift using 1.4m long wheelbarrow that weighs 80n with its CG.5m from the center of the wheel and the weight will be 1740N. I hope you are satisfied with my answer and feel free to ask for more.
Answer: Condensation of moisture in the air onto the glasses.
Explanation:
When you come from a cold environment into a warm ski lodge, the glasses are at a much lower temperature than that of the lodge.
Because the air in the room contains moisture (water vapor), it condenses on a surface whose temperature is lower than the dew point of the room.
