Does an object that feels cold to the touch contain thermal energy? explain your answer.

1 answer:

3 0

YES - explained (Temperature is an average of the kinetic energy isn't it? Thermal energy is the total. So you could have a really big "cold" object and it would have more energy then say a small "hot" object. But the average energy of the hot object would be greater than the average of the cold object. "You only need to know the amount of thermal energy a body contains to calculate its temperature" -You need to know something about the size of the objects and the particles that made it up? "The object contains less thermal energy than your hand" -It could be a large cold object, so it could have a greater amount of energy but over a larger area, so it's just the temperature that is lower. I've only studied thermodynamics a little, but I think that's sorta right...)

Really need help with this<br> Will give brainliest to whoever has the correct answer

Answer:

$a=0.4\ m/s^2$

Explanation:

1. Given that,

Initial speed of a bicycle, u = 4 m/s

The final speed of a bicycle, v = 6 m/s

Time, t = 6 s

We need to find the acceleration of the bicycle. We know that, acceleration is equal to the change in speed divided by time taken. So,

$a=\dfrac{v-u}{t}\\\\a=\dfrac{6-4}{5}\\\\a=0.4\ m/s^2$

So, the acceleration of the bicycle is equal to $0.4\ m/s^2$ .

the question you are looking for is

People often take milk of magnesia to reduce the discomfort associated with acid stomach or heartburn. The recommended dose is 1 teaspoon, which contains 4.00x 10^{2} mg of Mg(OH)_2. What volume of an HCl solution with a pH of 1.3 can be neutralized by one dose of milk of magnesia? If the stomach contains 2.00x10^{2}mL of pH 1.3 solution, is all the acid neutralized? If not, what fraction is neutralized?
