An good example would be using a Bunsen burner to heat water in a tin container. The flame initially heats the tin can by radiating heat. Conduction then transfers heat from the tin can to the water. The convection process causes the hot water to then climb to the top.
<h3>What is Bunsen Burner?</h3>
A laboratory piece of equipment known as a Bunsen burner, which bears Robert Bunsen's name, produces a single open gas flame and is used for heating, sterilization, and combustion. Natural gas, liquefied petroleum gas, such as propane, butane, or a combination, are all acceptable choices for the gas.
<h3>What three types of flames can you get from a Bunsen burner?</h3><h3>Bunsen burner flames come in three primary categories:</h3>
- Because it is simple to notice in a well-lit space, a yellow flame is also referred to as a safety flame.
- Flaming Blue. A burner's specific flame can reach temperatures of 500 degrees.
- Blue Flame in Flames The roaring blue flame setting on a Bunsen burner produces the hottest flames.

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Answer:
θ = 90º
Explanation:
The velocity is given by
v =
calculate
v = 3 i ^ + √2 j ^ + 2t k ^
acceleration is defined by
a = dv / dt
a = 2 k ^
one way to find the angle is with the dot product
v. a = | v | | a | cos θ
cos θ= v.a / | v | | a |
Let's look for the value of each term
v. a = 4 t
| v | = =
| a | = 2
they ask us for the angle for time t = 0
v. a = 0
| v | = √11 = 3.317
we substitute
cos θ = 0 /√11
cos θ = 0
therefore the angles must be θ = 90º
Answer: T = 305.22 K
Explanation: given that
from -90 degree Fahrenheit to -5
degree Kelvins
Using the formula
(9/5 C) + 32 = F
Let's first convert degree Fahrenheit to degree Celsius
90 = 9C/5 + 32
9C/5 = 90 - 32
9C/5 = 58
9C = 290
C = 290/9
C = 32.22 degree Celsius
Convert degree Celsius to Kelvins
T = 273 + C
T = 273 + 32.22
T = 305.22K
