Un pedazo de hielo el hielo s a -10°C se encuentra en un recipiente cerrado de material aislante sin aire y se enciende un bombillo adentro del recipiente a cierta distancia del hielo, se puede afirmar que la temperatura del hielo (A) aumenta, porque se transfiere calor por radiación (B) aumenta, porque se transfiere calor por convección (C) aumenta, porque se transfiere calor por conducción(contacto) (D) no cambia, porque no hay contacto entre el bombillo y el hielo.

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.
