A calorimeter is just an insulated container which contains the sample. You combust the sample inside the calorimeter, then you measure the temperature with respect to time. Make sure to stir constantly. Thus, you need a thermometer and a stirrer. The coffee cup calorimeter is labelled as shown in the picture attached. The goal of this experiment is to determine the specific heat capacity.
Answer:
Velocity = 120 km/h in north
Speed = 120 km/h
Explanation:
Given data:
Distance = 300 km north
Time taken = 2.5 hr
Speed and velocity = ?
Solution:
Speed = distance / time
Speed = 300 km / 2.5 h
Speed = 120 km/h
Velocity = change in position / change in time
Velocity = 300 km north / 2.5 hr
Velocity = 120 km/h in north
Answer:Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.
