There are quite a few ways to add moisture into the air without a humidifier
A few things that can help add moisture are hanging your clothing to dry. hang drying your damp clothes will add moisture to the air over time as it evaporates and it will make your house smell like fresh clothes.
Another thing is a bath, allow the water to cool off and leave the bathroom door open, the steam will add moisture to the air as the water cools.
This might seem silly but putting bowls or vases of water out on the windowsill on a sunny day mill moistens the air as it evaporates.
You can also get houseplants, moisture evaporates from the leaves and stems of plants. transpiration can help increase the humidity in your home.
not sure if this is the answer you were looking for but if so im glad i could help. have a great day!
I believe it's (C) Endothermic reaction
Explanation:
When energy is absorbed in an endothermic reaction, the temperature decreases.
Answer is: <span>j. double-replacement.
</span>Double displacement
reactions - cations and anions of the two reactants switch
places and form two new compounds.
Neutralization<span>is
is reaction in which an acid and a base react quantitatively with each other. In this reaction, there are no acids and bases, only salts.
</span><span>Synthesis
is reaction of two or more substances combining to make a more complex
substance. In this example, there is more complex substance in products.
</span>Oxidation-reduction reactions - <span>change in the oxidation number between the reactants and the products. In this example there is no change in oxidation number of elements.</span>
