Which of the following describes a way in which heat energy will be transferred by conduction?
Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance.
Which best explains what happens to most materials when they are heated?
Q. Which best explains what happens in most materials when they are heated? They expand.
Which statement describes the reason why an ice cube melts when set out in a warm room?
Which statement describes the reason why an ice cube melts when set out in a warm room? Heat from the room is absorbed by the ice cube. The ice cube molecules move more slowly.
Which kind of thermal energy transfer warms your hand when you hold a hot mug of tea?
Conduction
Conduction is the transfer of thermal energy between objects that are touching. In the teaspoon example, the particles of the tea are touching the particles of the metal spoon, which in turn are touching each other, and this is how heat is conducted from one object to the other.
Which occurs when a warm fluid cools down?
Which occurs when a warm fluid cools down? The mass of the fluid decreases.
Which statement explains how heat causes materials to expand?
Explanation: Thermal expansion is caused by heating solids, liquids or gases, which makes the particles move faster or vibrate more (for solids). This means that the particles take up more space and so the substance expands. 3) A liquid, when heated, will expand and can be made to rise up a tube.
Why do ice cubes melt?
The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.
What type of heat transfer is responsible for heating the air above the sand on the beach?
Conduction is the transfer of heat between objects that touch each other. When two materials have different temperatures, heat energy moves from the warmer one to the cooler one. In other words, the heat moves from the hot sand to the cooler bottoms of your feet.
What can be done to slow the current warming trend?
T/F: To slow the current warming trend, industrialized nations must reduce their overall rate of greenhouse gas emissions. THIS SET IS OFTEN IN FOLDERS WITH…
Is it true that more areas are warming than cooling?
Though warming has not been uniform across the planet, the upward trend in the globally averaged temperature shows that more areas are warming than cooling. According to the NOAA 2019 Global Climate Summary, the combined land and ocean temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880; however,
What is the temperature at the core of the Sun Quizlet?
Chapter 16 Temperature and Heat Q.3CQ Answers to odd-numbered Conceptual Questions can be found in the back of the book. To find the temperature at the core of the Sun, you consult some Web sites on the Internet. One site says the temperature is about 15 million °C, another says it is 15 million kelvin.
What has ice core data revealed about the Earth’s climate?
Ice core data have revealed which of the following? -current carbon dioxide concentrations are far outside of Earth’s recent operating range. -there’s a strong correlation between atmospheric carbon dioxide and temperature. -Earth’s climate shows a history of abrupt and rapid changes in temperature.
