False. Heat is measured in units of energy such as calories or joules, not in degrees Celsius. Temperature, on the other hand, is measured in degrees Celsius.
True. The difference between the freezing point (32°F) and boiling point (212°F) of water in the Fahrenheit scale is 180°F.
False. When water boils, the energy input causes the water molecules to gain enough kinetic energy to break free from the liquid phase and escape into the air as gas. This process does not involve the water molecules moving closer together.
False. Natural elements such as water, leaves, and rocks are capable of reflecting light to varying degrees, depending on their composition and surface properties.
True. When the temperature of water drops to 0 degrees Celsius, its molecules slow down and form regular patterns, creating a crystalline structure.
False. When water reaches 212 degrees Fahrenheit (100 degrees Celsius) and boils, it is absorbing both sensible heat (temperature increase) and latent heat (phase change from liquid to gas).
No, 90 degrees Fahrenheit is equal to about 32 degrees Celsius. 52 degrees Celsius is equivalent to around 125.6 degrees Fahrenheit.
False. Water expands when it cools from 38 to 32 degrees Fahrenheit. However, it contracts as it freezes below 32 degrees Fahrenheit.
I suggest you convert each of the Fahrenheit temperatures to Celsius (or the other way round, each of the Celsius temperatures to Fahrenheit), and then compare.
Of course they do! 20 degrees Fahrenheit is below freezing and Alaska does have a summer, no matter how short. They even go above 20 degrees Celsius in the summer and that is 68 degrees Fahrenheit.
This is untrue. To convert from degrees Fahrenheit to degrees Celsius, subtract 32, multiply by 5, and divide by 9.
The conversion of 37 degrees Celsius to Fahrenheit is 98.6 degrees. However, this is only an approximation. The actual conversion is 98.6 degrees Fahrenheit, which is considered false precision since the number 98.6 implies a higher level of accuracy than what is realistic in this case.
True. When water boils, the intermolecular hydrogen bonds between water molecules are broken, allowing them to escape as vapor.
Yes, for water at 60 degrees Fahrenheit to boil, it must first absorb sensible heat to reach its boiling point of 212 degrees Fahrenheit. Then it must absorb latent heat to undergo the phase change from liquid to gas. This process of absorbing both sensible and latent heat is necessary for the water to transition from a liquid state to a gaseous state.
false
False because if each base angle is 43 degrees then the apex angle must be 94 degrees
It is indeed false. The inner core is closer to ten thousand degrees.
