A wave looses its power as it comes to shore because it gets less deeper every second it gets closer to shore
You should use math on your mind and you should balance the bottle
Answer:
Option C is the correct answer.
Explanation:
We have ideal gas equation, PV = nRT
Volume of tank, V = 1 m³
Mass of water = 10 kg
Mass of 1 mole of water = 18 g = 0.018 kg
Number of moles,
Temperature, T = 160 °C = 160 + 273 = 433 K
Ideal gas constant, R = 8.314 JK⁻¹mol⁻¹
Substituting
P x 1 = 555 x 8.314 x 433
P = 2000000 Pa = 2000 kPa
The pressure in the tank is 2000 kPa
Option C is the correct answer.
The amount of thermal energy required to convert 1.75 kg of solid copper at 1358 K to liquid at 1358 K is 360.5 KJ
Q = m *
Q = Thermal energy
m = Mass
= Latent heat of copper
m = 1.75 kg
= 206 KJ / kg
Q = 1.75 * 206
Q = 360.5 KJ
Thermal energy is a type of energy that is responsible for a system's temperature. The flow of thermal energy is called as heat.
Therefore, the amount of thermal energy required is 360.5 KJ
