Answer:
The temperature should be 885K.
Explanation:
In this case we use Charles's Law according to which the volume and temperature of a certain amount of gas are related, keeping the pressure constant. We convert the unit of temperature from Celsius to Kelvin: 0 = 273K -> 40 ° C = 40 + 273 = 313K
V1 / T1 = V2 / T2
2,3L/313K= 6,5L/T2
T2=6,5L/(2,3L/313K)=884, 56K
Answer:
Hot material near Earth's surface is more dense and sinks, and when it cools, it becomes less dense and rises.
Explanation:
Convection is a process by which less dense material rises and more dense material sinks near Earth's surface. Water, air, rocks and other materials expands when temperature rises and they become less dense. When the water is heated it becomes vapors and carries away thermal energy from the water.
Answer:
See explanation
Explanation:
According to the law of conservation of mass; the total mass of reactants on the left hand side of the reaction equation is equal to the total mass of products on the right hand side of the reaction equation.
Hence, the total mass of each atom on either side of the reaction equation should be exactly the same.
Since there are two atoms of oxygen on the reactants side, the total mass of oxygen = 16 amu * 2 = 32 amu
Since there are two oxygen atoms on the products side, total mass of oxygen = 16 amu * 2 = 32 amu
Add hot water into the glass
Answer:
a item dropping
Explanation:
KE is movement and PE is height. As it's falling it gets KE and falls downward giving it more KE and less PE
