Two samples of water, X and Y, are at the same initial temperature above room
temperature. X has a mass of 200 g, and Y
has a mass of 500 g. Both samples are
allowed to cool to room temperature. How
do the change in temperature and the
change in thermal energy of Y compare to
those of X?

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

the answer is b, have negligible mass

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
