Answer: I think probaly wrong so probaly dont
listen to me
Explanation:
An Exothermic reaction releases energy into the surroundings and so the products have more potential energy then the reactants. The enthalpy change is a negative value. Whereas, an endothermic reaction involves the absorption of energy into the system and so the reactants have more potential energy than the products. The enthalpy change is a positive value. This is clearly represented in energy profile diagrams.
Answer:
A skateboarder coming down the ramp.
When something is going up against ( up or <u><em>down</em></u> ) something it causes friction.
Hope this helps!
Answer:
The greatest acceleration when the unbalanced force is applied will be experienced in :
A) The box with a mass of 2 kg
Explanation:
According to second law of motion the external unbalanced force is directly proportional to rate of change of momentum.
F = (Final momentum - initial momentum)/time
or
Force is equal to the product of mass and acceleration
F = m x a
Here a= acceleration
m = mass of the object
If Force is constant then acceleration is inversely proportional to mass
A) The box with a mass of 2kg
F = 8 N
a = 4 m/s2
B) The box with the mass of 4kg
a = 2 m/s2
C) The box with a mass of 6kg
a = 1.33 m/s2
D) The box with a mass of 8kg
a = 1 m/s2
a.The gas pressure will decrease.
Explanation:
If in a rigid container, the amount of gas particles and volume of the container is held constant, the pressure will decrease if the temperature is reduced.
- Gases are highly random particles and they require a high amount of kinetic energy to be in their state of matter.
- In a condition where volume of container is fixed, the amount of gas particles is fixed and the temperature reduced, the kinetic energy of the gas particles will directly reduce.
- The kinetic energy of gases is directly related to temperature.
