What has more thermal energy a small balloon or a large balloon

Physics

Firlakuza [10]3 years ago
7 0

Answer:

large balloon

Explanation:

Thermal energy is the amount of energy contained in a system solely by the effect of its temperature. However, this concept should not be confused with that of internal energy. Internal energy, in turn, is defined as the sum of kinetic energy (translational, rotational and vibrational) with the different forms of potential energy (attractive or repulsive) that can exist between the molecules of a body.

Kinetic energy is associated with the movement of molecules, while potential energy is energy that can be stored in a physical system. In the case of balloons filled with air or liquids, the larger the balloon, the greater the kinetic potential and consequently the thermal energy. For example, a large balloon filled with air will have more thermal energy, because it will have more air molecules that will move through the kinetic energy causing thermal energy.

The average kinetic energy of these individual particles causes an effect we can sense—warmth. ... The air in the air-filled balloon absorbed thermal energy from the flame and started moving faster. The increased movement of the molecules of air expanded the balloon and plastic of the balloon quickly melted. So the big one

Glass has a hardness that is in the middle of the hardness scale. What is the hardness of Glass?
sweet [91]

Answer: 5.5

Explanation:

Let's start by explaining that hardness is a property that materials have related to the opposition or resistance they offer to alterations such as penetration, abrasion, scratching, cutting, and permanent deformations, among others.

In this context, several hardness scales have been developed to catalog the materials (specifically minerals), being the Mohs scale  the best known. This scale, proposed by the German geologist Friedrich Mohs in 1825, consists of a ratio of ten minerals numbered in increasing order by hardness, from least to greatest.

This is how the scale starts at 1 with the talc (considered the softest material) and ends at 10 with the diamond as the hardest.

Now, if we are told that the glass is in the middle of the hardness scale that goes from 1 to 10, logically its value will be 5 (volcanic glass). However, according to the scale, the glass is at 5.5.

A tangent line drawn on a velocity-time graph has a rise of 19 m/s and a run of 4.0 m/s. How large is the acceleration? What typ
klemol [59]

Answer:

Acceleration = 4.8 m/s²

Explanation:

Given:

Change in velocity = 19 m/s

Change in time = 4 s

Find:

Acceleration

Computation:

Acceleration = Change in velocity / Change in time

Acceleration = 19/4

Acceleration = 4.8 m/s²

Positive acceleration

A train travels 200km/hr. how much distance will the train be from the station in 2.5 hours?
SCORPION-xisa [38]

Answer:

500km

Explanation:

Given parameters:

Speed  = 200km/hr

Time taken  = 2.5hrs

Unknown:

Distance  = ?

Solution:

To solve this problem, we use the speed, time and distance equation.

   Therefore;

  Distance  = Speed x time

So;

  Distance  = 200 x 2.5  = 500km
