When water evaporates What does it turn into? Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. How fast does a glass of water evaporate? 1.2 hours What are some real […]
Can electric current flow through human body?
Can electric current flow through human body? The human body is a good conductor of electric current simply because it is 70% water. Human tissue is very sensitive to the flow of electric current and is more susceptible to electric shock when wet. Does human body have current? Electricity is everywhere, even in the human […]
What are the similarities and differences between fission and fusion?
What are the similarities and differences between fission and fusion? Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of […]
What do liquid objects have in common?
What do liquid objects have in common? Liquids have the following characteristics: No definite shape (takes the shape of its container). Has definite volume. Particles are free to move over each other, but are still attracted to each other. Why doesn’t mass alone determine whether an object will float or sink? Density is the only […]
What are the 4 properties of the atom?
What are the 4 properties of the atom? Typical sizes of atom and nucleus. Most of atom’s mass is in the nucleus. Constituents: protons, neutrons, electrons. Electric force holds atom together. Nuclear force holds nucleus together. Atoms, ions. Atomic number. What are three examples of properties? These properties include color, density, melting point, boiling point, […]

What color temperature is best for plants?
What color temperature is best for plants? As a general recommendation, choose a full spectrum grow light with a color temperature in the blue range (5,000 – 7,000K) to promote vegetative growth and choose a color temperature in the red range (3,500 – 4,500K) to promote fruiting and flowering. Visible Light Spectrum. Can plants grow […]
What is the smallest electromagnetic wave?
What is the smallest electromagnetic wave? Gamma Rays Is the electromagnetic spectrum infinite? In general the frequency spectrum for Electromagnetic (e.g light, radio, etc) is continuous and thus between any two frequencies there are an uncountable infinity of possible frequencies (just as there are an uncountable number of numbers between 1 and 2). What does […]
How do we know carbon dioxide is a greenhouse gas?
How do we know carbon dioxide is a greenhouse gas? This ability to absorb and re-emit infrared energy is what makes CO2 an effective heat-trapping greenhouse gas. Not all gas molecules are able to absorb IR radiation. For example, nitrogen (N2) and oxygen (O2), which make up more than 90% of Earth’s atmosphere, do not […]
Can you turn off a electromagnet?
Can you turn off a electromagnet? Re: Turning off electromagnet Use a relay. Wire the electromagnet to the relay’s normally closed pins, then run current through the pushbutton switch to the relay coil – when you push the switch, it’ll pull the relay the other way and the electromagnet will shut off. How do you […]
