its true............................................true
Step 1: 405kpa times 4cm^3 so 405/4=1620
Step 2: 1620 divide 6 so 1620/6=270
The final answer is 270Kpa
A lot of carbon stored inside the Earth may soon re-enter the atmosphere, according to a new, global study on soil-based carbon. The massive release of carbon could be the equivalent of adding another fully industrialized country the size of the United States to the map over the coming decades.
Plants, animals, and microbes absorb much of the carbon dioxide released into the Earth's atmosphere by burning fossil fuels. As these plants and animals die, their carbon-based bodies become part of the soil, storing the equivalent of millions of tons of greenhouse gases in the dirt. As atmospheric carbon dioxide is a primary driver of climate change, some have pointed to this soil absorption as a helpful carbon sink, somewhat alleviating the human-caused warming of the planet. But as surface temperatures continue to rise, a lot of the carbon stored in the soil may be set to re-enter the atmosphere in a big way.
.B) decomposition of organic matter
The right option is; b. the water caused an increase in temperature of the air inside the ball and an increase in pressure.
The dent (hollow area formed by pressing or hitting) from the ping-pong ball disappeared because energy was transferred from the hot boiling water in which the ball was placed to the air inside the ball. This transferred energy will increase the temperature of the air inside the ball and the air molecules will begin to move faster with a greater force. Hence, causing an increase in pressure.
Hibernate because when they sleep they don't use any calories so thus,they can survive the winter without waking up for food. This is because also their metabolism slows down so much that it consumes little to no calories a hour keeping its vitals stable and not having to wake up to ''refuel" it's self.
