What happens to pressure if the volume is decreased?
What happens to pressure if the volume is decreased? If volume increases, then pressure decreases and vice versa, when the temperature is held constant. Therefore, when the volume is halved, the pressure is doubled; and if the volume is doubled, the pressure is halved. What happens to pressure when you reduce volume? Explanation: Gas particles […]
What happens when the frequency of a sound wave decreases?
What happens when the frequency of a sound wave decreases? If frequency decreases, pitch decreases and produces a lower sound. Frequency and wavelength are inversely related, meaning that if frequency increases, wavelength becomes shorter and vice versa. Therefore, if frequency increases, pitch increases and creates a higher sound and wavelengths become shorter. Why is sound […]

What is the characteristics of metamorphic rocks?
What is the characteristics of metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture. What are 3 facts about metamorphic rocks? The word metamorphic literally […]
How do you write a reaction rate?
How do you write a reaction rate? Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time. What is meant by […]
