In which beaker did the coffee powder dissolve faster?
beaker with cold water
beaker with hot water
the temperature of the water did not affect the time it took to dissolve the powder
In which beaker did the coffee powder dissolve slower?
beaker with cold water
beaker with hot water
the temperature of the water did not affect the time it took to dissolve the powder
How do you relate the temperature to the rate at which the coffee powder dissolved in water?
The lower the temperature, the faster the rate the coffee powder dissolved in the water.
The higher the temperature, the slower the rate the coffee powder dissolved in the water.
The higher the temperature, the faster the rate the coffee powder dissolved in the water.
The temperature did not affect the rate at which the powder dissolved in the water.
In which beaker are the particles of water moving faster?
beaker with cold water
beaker with hot water
In which beaker are the particles of water moving slower?
beaker with cold water
beaker with hot water
How would you compare the movement of particles in hot water and cold water?
hot water-faster;
cold water-slower
hot water-slower;
cold water- faster
hot and cold water - slow
hot and cold water - fast
How would you relate the movement of particles to the kinetic energy of the particles in hot water? in cold water?
The particles in hot water and cold water has the same kinetic energy.
The particles in hot water has lower kinetic energy. The particles in cold water has higher kinetic energy.
The particles in hot water has higher kinetic energy. The particles in cold water has lower kinetic energy.
How is the kinetic energy of the particles related to temperature?
The higher the temperature, the greater the kinetic energy of the particles.
The lower the temperature, the higher the kinetic energy of the particles.
The higher the temperature, the lower the kinetic energy of the particles.
The temperature of the water affects the kinetic energy of the particles of water.
true
false
cannot be determined
What can you say about the rate at which the coffee powder dissolve in each beaker?
different rate
same rate
changes from time to time
