The country among the choices which has about 20 active volcanoes is the Philippines. The PHIVOLCS which is the Philippine national institution dedicated to studies on volcanoes have identified at least 23 volcanoes as active with 21 of them having historical eruptions.
Answer:
Higher temperature increases the speed of solubility
Explanation:
"Solubility" refers to the ability of a solute to be dissolved in a solvent. Solubility and temperature are <em>directly proportional</em>. This means that <em>as the temperature increases, the solubility of a substance increases too</em>. In the same manner, <em>as the temperature decreases, the solubility of a substance decreases too.</em>
High temperature produces<u> high heat (increase kinetic energy) that triggers the solvent to break the solutes apart.</u> This is mostly true for many solid-state solutions.
Answer:
False
Explanation:) hope this helps
Acceleration is defined as the rate of change in velocity, rather than speed. When straight-line motion is considered, it is common to use speed and velocity interchangeably. When the direction is not changing, acceleration may be expressed as the rate at which speed changes.
Answer:
True
Explanation:
Pyroclastic textures occur when explosive eruptions blast the lava into the air resulting in fragmental, typically glassy material which fall as volcanic ash, lapilli and volcanic bombs.
