Answer:
A. What is the concentration of nitric acid?
Explanation:
its right
Explanation:
Water molecules are polar, so they form hydrogen bonds. This is a unique property of water. Water has an unique boiling point and high polarity.
Answer : Gaseous water molecules condense when they cooled. Liquid water molecules evaporate when they heated.
Explanation :
Condensation : It is a process in which a phase changes from gaseous state to liquid state. This process occurs when the water molecules in the air cool down and they join together to form liquid water.
Evaporation : It is a process in which a phase changes from liquid state to gaseous state. This process occurs when the water is heated, the molecules in the water move and vibrate quickly that they escape into the atmosphere as water vapor.
Answer:
Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object.
