How is heat being transfered when you place your finger in the cold beaker why?
If the beaker has a cold water, or something else cold, in it than the heat that is in our finger will run out of you finger into the cold water. This leaves your finger 'empty' of heat, giving you the sensation of being cold. You need to remember that only heat moves. When you are cold you wear a jumper that keeps the heat in your body, not keep the cool out.
When Predict how heat would flow if beaker a is moved so that it is touching beaker b?
Heat would flow from beaker A to beaker B, moving in the direction of higher temperature to lower temperature. The heat transfer would continue until both beakers reached thermal equilibrium, with their temperatures equalizing.
What happens to the thermal energy in a beaker as it cools down?
As the beaker cools down, the thermal energy within it decreases. This results in a transfer of heat from the beaker to its surroundings, causing the temperature of the beaker to drop.
I have 150 grams of water in a beaker What is it's mass?
it would be the same
What is a displacement beaker?
a displacement beaker (canister) is used to determine volume of irregular objects. Water is put into the beaker up to the spout, and then an object is placed inside; the water that pours out is collected in a more accurate measurement device, this water is equal (or close to) the volume of the object.
How do you heat a liquid to 90 degrees?
if your in a lab, put water in a beaker, place the beaker on a tripod and heat with Bunsen burner, (use thermometer to measure
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.
If beaker a had 250ml of water beaker b had 500ml water are warmed from 10 celsius to 20 celsius what one requires more heat?
Because there is a greater volume of water in beaker B, the beaker would have to be heated for a longer period of time to reach the same temperature as beaker A. If your desire is to have both beakers warmed to the same temperature at the same time, beaker B would require the addition of more heat (because there is more water inside it).
What is the best way to heat a beaker of water on a Bunsen burner?
The best way to heat a beaker of water on a Bunsen burner is to adjust the air hole to get a blue flame, place the beaker on a wire gauze to distribute heat evenly, and continuously stir the water with a glass rod to ensure uniform heating. Additionally, you should monitor the temperature with a thermometer to prevent overheating.
How does the temperature of the water in the large beaker compare or contrast with the temperature of the water in the small beaker?
The temperature of the water in the large beaker may differ from that in the small beaker depending on factors such as the volume of water, the surrounding environment, and heat sources. Generally, larger volumes of water can retain heat more effectively than smaller volumes, leading to a slower temperature change. However, if both beakers were subjected to the same conditions, their temperatures could be similar. Ultimately, the comparison depends on specific circumstances affecting each beaker.
What factors affect the rate at which Bunsen burner heats water in a beaker?
The rate at which a Bunsen burner heats water in a beaker is affected by factors such as the size of the flame, proximity of the flame to the beaker, the material of the beaker, and the starting temperature of the water. Additionally, the efficiency of the heat transfer process can be influenced by the presence of a lid or stirrer in the beaker.
How is heat being transfered when you place your finger in the cold beaker why?

How do you insulate a beaker of water?
You can insulate a beaker of water by wrapping it with an insulating material such as a towel, foam, or bubble wrap. This will help to prevent heat loss from the water to the surrounding environment, keeping it warmer for a longer period. Additionally, placing the beaker on a coaster or mat can provide further insulation by reducing heat transfer to a colder surface.
How does the heat reach the thermometer in the heated beaker?
Heat reaches the thermometer in the heated beaker primarily through conduction and convection. As the beaker is heated, the water molecules gain energy and transfer that energy to the thermometer through direct contact. Additionally, as the warmer water rises and cooler water descends, convection currents help distribute heat throughout the liquid, ensuring that the thermometer accurately reflects the water's temperature. This process allows the thermometer to register the temperature of the liquid efficiently.
What happens to the water in the beaker during melting?
During melting, the water in the beaker absorbs heat and undergoes a phase change from solid (ice) to liquid. As it melts, the temperature remains constant until all the ice has transformed into water.
In an experiment what is a heat used for?
A heat is used to increase the thermal energy in whatever you are testing. In a typical classroom situation, the heat will be supplied by a Bunsen Burner, which provides a flame. This flame is then used to heat whatever object needs heating. For example, boiling a beaker of water by applying the heat under said beaker.
What happened to the water in the beaker?
The water in the beaker evaporated or was poured out.
