what is the volume of a marble that has a mass of 3.g and a Density of 2.7 g/ml ?
make sure to round to the nearest tenth
Answer:
1.111 or since you want me to round 1.1 if not right let me know please.
Explanation:
Answer:
1.1
Explanation:
all you have to do is divide the mass by density to get the volume yurr
The phase of matter can be changed by:
a) increasing temperature
b) decreasing mass
c) increasing volume
d) all of the above
Answer: A
Explanation: Mass and volume is the amount, amount doesn’t make the phase of a matter change.
the ____ temperature of an object the lower its thermal energy
Thermal energy is the average sum of all kinetic energy of all the molecules of gases. The lower the temperature of an object the lower its thermal energy.
What is Thermal energy?
Thermal energy is a energy which is possess by a moving object. It is directly proportional to kinetic energy of the molecules. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy.
Mathematically,
K.E=2/3KT
Where,
K= Boltzmann constant
T is the temperature
Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases. The lower the temperature of an object the lower its thermal energy.
Therefore, the lower the temperature of an object the lower its thermal energy.
