In an experiment a group gathered the following data: Mass of test tube (g) = 21.3
Mass of test tube and metal (g) = 52.7
Mass of beaker (g) = 120.40
Mass of beaker and water (g) = 137.54
Initial temperature of hot metal (°C) = 80.4
Initial temperature of cold water (°C) = 1.19
Final temperature of the mixture (°C) = 21.4
To the thousandths place, what is the specific heat of the metal used in the experiment above?

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
