A closed, rigid tank contains a two-phase liquid-vapor mixture of Refrigerant-22 initially at −18°C with a quality of 50.9%. Energy transfer by heat into the tank occurs until the refrigerant has become purely a saturated vapor. What is the final temperature, in [°C]? (2°C) What is the net amount of heat per unit mass of refrigerant to/from the tank, in [kJ/kg]? (103 kJ/kg)

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
