Hello friend, the answer would be 1609.34. Hope it helps. :) BTW, I've also double checked for you. :)
Explanation:
Boiling water:water heats up and bubbles physical change
Baking a cake: starts to cook into bread chemical change
Burning wood: turns into ash and burned wood chemical change
Painting a door: door changes color physical change
Answer: If you were in a car and maintained an average speed of 60mph (96 kmh) over the course of your it would take you around 3.72 hours to get from Dallas to Shreveport.
Explanation: i just had to calculate the time and the distance and how long it would take with different speeds and this is the closest one i got.
Explanation:
Boiling point is defined as the temperature at which vapor pressure of liquid becomes equal to the atmospheric pressure.
When high temperature is provided to a liquid then forces of attraction between the molecules decreases and kinetic energy of its molecules increases. As a result, collision between the particles increases.
Also, it is known that kinetic energy is directly proportional to temperature. Therefore, when temperature increase kinetic energy also increases.
Hence, we can conclude that statements correctly describing water boiling in a pot are as follows.
- The water’s internal kinetic energy is increasing.
- The water’s temperature is increasing.
- Individual water molecules are escaping.
Correct Answer: option 4: <span>E and D show that the energy of the products is less than that of the reactants.
Reason:
For the reaction: Q + R </span>→ N + M
<span> (reactant) (product)
From the graph, it is clearly evitable that E represent energy of reactant, while D represents energy of products. Also, value of D is less as compared to E. This signifies that, products (N+M) has less energy as compared to reactants (Q+R). Also, the reaction is exothermic in nature.
