Answer:
this is because spreading it makes more sunlight hit the cloth which results in it drying faster
<u>Any of five chemical substances that are not metals and that combine with hydrogen to form strong acid compounds from which simple salts can be made</u>
Answer:
see note under explanation
Explanation:
When describing system and surroundings the system is typically defined as the 'object of interest' being studied and surroundings 'everything else'. In thermodynamics heat flow is typically defined as endothermic or exothermic. However, one should realize that the terms endothermic and exothermic are in reference to the 'system' or object of interest being studied. For example if heat is transferred from a warm object to a cooler object it is imperative that the system be defined 1st. So, with that, assume the system is a warm metal cylinder being added into cooler water. When describing heat flow then the process is exothermic with respect to the metal cylinder (the system) but endothermic to the water and surroundings (everything else).
The correct answer is C) A substance changes color when heated, but changes back when cooled. Hope this helps.
It is made of polar molecules
