What energy changes is taking place in a blender

Chemistry
1 answer:
Bas_tet [7]3 years ago
6 0
Electrical energy is supplied to the blender. This is converted into kinetic energy to turn the blades that blend the food, so energy is transferred from electrical to kinetic. This is the useful energy change that we most want to happen.
However, not 100% of the electrical energy is transferred to kinetic energy. Some of the electrical energy is converted to sound energy (which is why blenders are noisy) and some is converted to heat (which is why you shouldn't leave them running for ages). These are less useful energy changes as they do not help to blend the food.

Which process moves molecules and has these traits?
Ostrovityanka [42]
Diffusion is the right answer, because technically the only acceptable answers here are diffusion and osmosis. But osmosis occurs in a semi-membrane, leaving no choice but diffusion.

Although the nucleus of an atom is very important, it is the ___ of the atom that determine its chemical properties
aleksandrvk [35]
<span>Although the nucleus of an atom is very important, it is the electrons of the atom that determine its chemical properties.

Number of electrons of an atoms (the number of electrons in the outermost level mostly) determine the type of the element (whether it is a metal, metalloid or non-metal).
Based on this, the types of bonds that the atom can form (whether ionic or covalent) is determined, the type of reactions that the element can form is known and the elements that can react with it are also know.</span>

The laser in a 3D printer uses light with a frequency of 3.844 × 1014 Hz. Calculate the wavelength of this light in nm. Show all
Natali5045456 [20]

Answer:

The wavelength of this light is 780.4 nm.

Explanation:

Given that,

The frequency of laser light, f=3.844 \times 10^{14}\ Hz

We need to find the wavelength of this light.

We know that,

c=f\lambda

Where

\lambda is the wavelength of light

So,

\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3.844 \times 10^{14}}\\\\=7.804\times 10^{-7}\ m\\\\=780.4\ nm

So, the wavelength of this light is 780.4 nm.
