Answer:
Animals gain energy from the food they eat. Some animals eat plants while others eat other animals. This is passing of energy from the sun to plants to animal to other animals is called a food chain
I think it's hydrogen. Hope this helps :)
Answer:
The new temperature will be 2546 K or 2273 °C
Explanation:
Step 1: Data given
The initial temperature = 1000 °C =1273 K
The volume = 20L
The volume increases to 40 L
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 20L
⇒with T1 = the initial temperature = 1273 K
⇒with V2 = the increased volume = 40L
⇒with T2 = the new temperature = TO BE DETERMINED
20L/ 1273 K = 40L / T2
T2 = 40L / (20L/1273K)
T2 = 2546 K
The new temperature will be 2546 K
This is 2546-273 = 2273 °C
Since the volume is doubled, the temperature is doubled as well
The answer is choice (1).
In case you're interested in the solution for future reference:
-- Density = (mass) / (volume)
-- The scale shows that the mass of the sample is 60 grams.
-- The graduated cylinder has 24 mL in it <em>without</em> the sample.
The graduated cylinder has 34 mL in it <em>with</em> the sample.
The volume of the sample is (34mL - 24mL) = 10 mL .
-- Density = mass/volume = 60g / 10mL = 6 g/mL
True
