What will happen if a spoon measuring 5 °C is placed into a glass of water measuring 20 °C? A. Heat will move from the water to the spoon until the spoon reaches 20 °C.
B. Heat will move from the spoon into the water until both are balanced at 25 °C.
Heat will move from the spoon into the water until the temperatures of both are balanced
at 15 °C.
C.
D.
Heat will move from the water to the spoon until the temperatures of both are balanced
between 5 °C and 20 °C.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

80cm/s.

24cm/s.

53.3cm/s.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
